Product Description
Product Description
SIDACtor components are solid state crowbar devices designed to protect telecom
equipment during hazardous transient conditions. Capitalizing on the latest in thyristor
advancements, Teccor makes SIDACtor devices with a patented ion implant technology.
This technology ensures effective protection within nanoseconds, up to 5000 A surge
current ratings, and simple solutions for regulatory requirements such as GR 1089,
TIA-968 (formerly known as FCC Part 68), ITU-T K.20, ITU-T K.21, and UL 60950.
Operation
In the standby mode, SIDACtor devices exhibit a high off-state impedance, eliminating
excessive leakage currents and appearing transparent to the circuits they protect. Upon
application of a voltage exceeding the switching voltage (VS), SIDACtor devices crowbar
and simulate a short circuit condition until the current flowing through the device is either
interrupted or drops below the SIDACtor device’s holding current (IH). Once this occurs,
SIDACtor devices reset and return to their high off-state impedance.

Advantages
Compared to surge suppression using other technologies, SIDACtor devices offer absolute
surge protection regardless of the surge current available and the rate of applied voltage
(dv/dt). SIDACtor devices:
•
•
•
•
•
•
Cannot be damaged by voltage
Eliminate hysteresis and heat dissipation typically found with clamping devices
Eliminate voltage overshoot caused by fast-rising transients
Are non-degenerative
Will not fatigue
Have low capacitance, making them ideal for high-speed transmission equipment

authorized officer of Supplier), Supplier reserves the right to alter its price, whether or not such price was quoted
as “firm”.
(C) Prices do not include federal, state or local taxes, now or hereafter enacted, applicable to the goods sold. Taxes will
be added by Supplier to the sales prices whenever Supplier has legal obligation to collect them and will be paid by
Buyer as invoiced unless Buyer provides Supplier with a proper tax exemption certificate.
(2) PRODUCTION: Supplier may, at its sole discretion and at any time, withdraw any catalog item from further production without
notice or liability to Buyer.
(3) INTEREST:
(A) All late payments shall bear interest thirty (30) days after the due date stated on the invoice until paid at the lower of one
and one-half percent per month or the maximum rate permitted by law. All interest becoming due shall, if not paid when
due, be added to principal and bear interest from the due date. At Supplier's option, any payment shall be applied first
to interest and then to principal.
(B) It is the intention of the parties to comply with the laws of the jurisdiction governing any agreement between the
parties relating to interest. If any construction of the agreement between the parties indicates a different right given
to Supplier to demand or receive any sum greater than that permissible by law as interest, such as a mistake in
calculation or wording, this paragraph shall override. In any contingency which will cause the interest paid or
agreed to be paid to exceed the maximum rate permitted by law, such excess will be applied to the reduction of
any principal amount due, or if there is no principal amount due, shall be refunded.
(4) TITLE AND DELIVERY: Title to goods ordered by Buyer and risk of loss or damage in transit or thereafter shall pass to Buyer
upon Supplier's delivery of the goods at Supplier's plant or to a common carrier for shipment to Buyer.
(5) CONTINGENCIES: Supplier shall not be responsible for any failure to perform due to causes reasonably beyond its control.
These causes shall include, but not be restricted to, fire, storm, flood, earthquake, explosion, accident, acts of public enemy,
war rebellion, insurrection, sabotage, epidemic, quarantine restrictions, labor disputes, labor shortages, labor slow downs
and sit downs, transportation embargoes, failure or delays in transportation, inability to secure raw materials or machinery for
the manufacture of its devices, acts of God, acts of the Federal Government or any agency thereof, acts of any state or local
government or agency thereof, and judicial action. Similar causes shall excuse Buyer for failure to take goods ordered by
Buyer, from the time Supplier receives written notice from Buyer and for as long as the disabling cause continues, other than
for goods already in transit or specially fabricated and not readily saleable to other buyers.
Supplier assumes no responsibility for any tools, dies, and other equipment furnished Supplier by Buyer.
(6) LIMITED WARRANTY AND EXCLUSIVE REMEDY: Supplier warrants all catalog products to be free from defects in materials
and workmanship under normal and proper use and application for a period of twelve (12) months from the date code on the
product in question (or if none, from the date of delivery to Buyer.) With respect to products assembled, prepared, or manu-
factured to Buyer's specifications, Supplier warrants only that such products will meet Buyer's specifications upon delivery.
As the party responsible for the specifications, Buyer shall be responsible for testing and inspecting the products for adher-
ence to specifications, and Supplier shall have no liability in the absence of such testing and inspection or if the product
passes such testing or inspection. THE ABOVE WARRANTY IS THE ONLY WARRANTY EXTENDED BY SUPPLIER, AND
IS IN LIEU OF AND EXCLUDES ALL OTHER WARRANTIES AND CONDITIONS, EXPRESSED OR IMPLIED (EXCEPT AS
PROVIDED HEREIN AS TO TITLE), ON ANY GOODS OR SERVICES SOLD OR RENDERED BY SUPPLIER, INCLUDING
ANY IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THIS WARRANTY
WILL NOT CREATE WARRANTY COVERAGE FOR ANY ITEM INTO WHICH ANY PRODUCT SOLD BY SUPPLIER MAY
HAVE BEEN INCORPORATED OR ADDED.
SUPPLIER'S ENTIRE LIABILITY AND BUYER'S EXCLUSIVE REMEDY UNDER THIS WARRANTY SHALL BE, AT
SUPPLIER'S OPTION, EITHER THE REPLACEMENT OF, REPAIR OF, OR ISSUANCE OF CREDIT TO BUYER'S
ACCOUNT WITH SUPPLIER FOR ANY PRODUCTS WHICH ARE PROPERLY RETURNED BY BUYER DURING THE
WARRANTY PERIOD. All returns must comply with the following conditions:

Standard Terms and Conditions
(A) Supplier is to be promptly notified in writing upon discovery of defects by Buyer.
(B) Buyer must obtain a Return Material Authorization (RMA) number from the Supplier prior to returning product.
(C) The defective product is returned to Supplier, transportation charges prepaid by Buyer.
(D) Supplier's examination of such product discloses, to its satisfaction, that such defects have not been caused by
misuse, neglect, improper installation, repair, alteration, or accident.
(E) The product is returned in the form it was delivered with any necessary disassembly carried out by Buyer at Buyer's
expense.
IN NO EVENT SHALL SUPPLIER, OR ANYONE ELSE ASSOCIATED IN THE CREATION OF ANY OF SUPPLIER'S
PRODUCTS OR SERVICES, BE LIABLE TO BUYER FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY
NATURE INCLUDING LOSS OF PROFITS, LOSS OF USE, BUSINESS INTERUPTION, AND THE LIKE. BUYER
ACKNOWLEDGES THAT THE ABOVE WARRANTIES AND LIMITATIONS THEREON ARE APPROPRIATE AND
REASONABLE IN EFFECTUATING SUPPLIER'S AND BUYER'S MUTUAL INTENTION TO CONDUCT AN EFFICIENT
TRANSACTION AT PRICES MORE ADVANTAGEOUS TO BUYER THAN WOULD BE AVAILABLE IN THE PRESENCE
OF OTHER WARRANTIES AND ASSURANCES.
(7) PATENTS: Buyer shall notify Supplier in writing of any claim that any product or any part of use thereof furnished under this
agreement constitutes an infringement of any U.S. patent, copyright, trade secret, or other proprietary rights of a third party.
Notice shall be given within a reasonable period of time which should in most cases be within ten (10) days of receipt by
Buyer of any letter, summons, or complaint pertaining to such a claim. At its option, Supplier may defend at its expense any
action brought against Buyer to the extent that it is based on such a claim. Should Supplier choose to defend any such claim,
Supplier may fully participate in the defense, settlement, or appeal of any action based on such claim.
Should any product become, or in Supplier's opinion be likely to become, the subject of an action based on any such
claim, Supplier may, at its option, as the Buyer's exclusive remedy, either procure for the Buyer the right to continue
using the product, replace the product or modify the product to make it noninfringing. IN NO EVENT SHALL SUPPLIER
BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES BASED ON ANY CLAIM OF INFRINGEMENT.
Supplier shall have no liability for any claim based on modifications of a product made by any person or entity other than
Supplier, or based on use of a product in conjunction with any other item, unless expressly approved by Supplier.
Supplier does not warrant goods against claims of infringement which are assembled, prepared, or manufactured to
Buyer's specifications.
(8) NON-WAIVER OF DEFAULT: Each shipment made under any order shall be treated as a separate transaction, but in the
event of any default by Buyer, Supplier may decline to make further shipments without in any way affecting its rights under
such order. If, despite any default by Buyer, Supplier elects to continue to make shipments, its action shall not constitute a
waiver of that or any default by Buyer or in any way affect Supplier's legal remedies for any such default. At any time, Sup-
plier's failure to exercise any right to remedy available to it shall not constitute a waiver of that right or remedy.
(9) TERMINATION: If the products to be furnished under this order are to be used in the performance of a Government contract
or subcontract, and the Government terminates such contract in whole or part, this order may be canceled to the extent it
was to be used in the canceled portion of said Government contract and the liability of Buyer for termination allowances shall
be determined by the then applicable regulations of the Government regarding termination of contracts. Supplier may cancel
any unfilled orders unless Buyer shall, upon written notice, immediately pay for all goods delivered or shall pay in advance
for all goods ordered but not delivered, or both, at Supplier's option.
(10) LAW: The validity, performance and construction of these terms and conditions and any sale made hereunder shall be gov-
erned by the laws of the state of Texas.
(11) ASSIGNS: This agreement shall not be assignable by either Supplier or Buyer. However, should either Supplier or Buyer be
sold or transferred in its entirety and as an ongoing business, or should Supplier or Buyer sell or transfer in its entirety and as
an ongoing concern, any division, department, or subsidiary responsible in whole or in part for the performance of this Agree-
ment, this Agreement shall be binding upon and inure to the benefit of those successors and assigns of Supplier, Buyer, or
such division, department, or subsidiary.
(12) MODIFICATION OF STANDARD TERMS AND CONDITIONS: No attempted or suggested modification of or addition to any
of the provisions upon the face or reverse of this form, whether contained or arising in correspondence and/or documents
passing between Supplier and Buyer, in any course of dealing between Supplier or Buyer, or in any customary usage preva-
lent among businesses comparable to those of Supplier and/or Buyer, shall be binding upon Supplier unless made and
agreed to in writing and signed by an officer of Supplier.
(13) QUANTITIES: Any variation in quantities of electronic components, or other goods shipped over or under the quantities
ordered (not to exceed 5%) shall constitute compliance with Buyer's order and the unit price will continue to apply.

All measurements are made at an ambient temperature of 25 °C. IPP applies to -40 °C through +85 °C temperature range.
I
PP is a repetitive surge rating and is guaranteed for the life of the product.
Listed SIDACtor devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
V
DRM is measured at IDRM.
VS is measured at 100 V/µs.
Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request.
Off-state capacitance is measured at 1 MHz with a 2 V bias and is a typical value for “SA” and “SB” product. “SC” capacitance is
approximately 2x the listed value. The off-state capacitance of the P0080SB is equal to the “SC” device.

High Surge Current (D-rated) SIDACtor Device
High Surge Current (D-rated) SIDACtor Device
DO-214AA SIDACtor solid state protection devices with a D surge rating protect
telecommunications equipment such as modems, line cards, fax machines, and other CPE.
These SIDACtor devices withstand simultaneous surges incurred in GR 1089 lightning
tests. (See "First Level Lightning Surge Test" on page 4-5.) Surge ratings are twice that of a
device with a C surge rating. This allows a discrete surface mount version of Teccor’s
patented “Y” configuration. (US Patent 4,905,119)
SIDACtor devices are used to enable equipment to meet various regulatory requirements
including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968 (formerly
known as FCC Part 68).

MicroCapacitance (MC) SIDACtor Device
MicroCapacitance (MC) SIDACtor Device
The TO-92 MC SIDACtor series is intended for applications sensitive to load values.
Typically, high speed connections require a lower capacitance. CO values for MC devices
are 40% lower than a standard EC part.
This MC SIDACtor series is used to enable equipment to meet various regulatory
requirements including GR 1089, ITU K.20, K.21, and K.45, IEC 60950, UL 60950, and TIA-
968 (formerly known as FCC Part 68) without the need of series resistors.

Multiport SIDACtor Device
Multiport SIDACtor Device
The multiport line protector is an integrated multichip solution for protecting multiple
twisted pair from overvoltage conditions. Based on a six-pin surface mount SOIC
package, it is equivalent to four discrete DO-214AA or two TO-220 packages. Available
in surge current ratings up to 500 A, the multiport line protector is ideal for densely
populated, high-speed line cards that cannot afford PCB inefficiencies or the use of
series power resistors.

Four-Port Metallic Line Protector
Four-Port Metallic Line Protector
The four-port hybrid Single In-line Package (SIP) line protector protects multiple twisted pair
from overcurrent and overvoltage conditions. Based on a SIP, it is equivalent to four
discrete DO-214AA SIDACtor devices and four surface mount fuses. Available in surge
current ratings up to 500 A, this four-port SIP line protector is ideal for densely populated
line cards that cannot afford PCB inefficiencies or the use of series power resistors.

Battrax Dual Positive/Negative SLIC Protector
Battrax Dual Positive/Negative SLIC Protector
(+VREF
)
This Battrax device protects Subscriber Line Interface Circuits (SLIC) that use both a
5
positive and negative Ring voltage. It limits transient voltages with rise times of 100 V/
µs to V
±10 V.
REF
Ground
4, 6
Teccor’s six-pin Battrax devices are constructed using four SCRs and four gate diodes.
The SCRs conduct when a voltage that is more negative than -V (and/or more
REF
positive than +V
) is applied to the cathode (Pins 1 and 3) of the SCR. During
REF
conduction, the SCRs appear as a low-resistive path which forces all transients to be
shorted to ground.

TeleLink Fuse
The TeleLink Surface Mount (SM) surge resistant fuse offers circuit protection without
requiring a series resistor. When used in conjunction with the SIDACtor Transient Voltage
Suppressor (TVS), the TeleLink SM fuse and the SIDACtor TVS provide a complete
regulatory-compliant solution for standards such as GR 1089, TIA-968 (formerly known as
FCC Part 68), UL 60950, and ITU K.20 and K.21. No series resistor is required for the
F1250T and F1251T to comply with these standards.

SIDACtor Data Book and Design Guide
Customer Premises Equipment (CPE)
Customer Premises Equipment (CPE)
CPE is defined as any telephone terminal equipment which resides at the customer’s site
and is connected to the Public Switched Telephone Network (PSTN). Telephones, modems,
caller ID adjunct boxes, PBXs, and answering machines are all considered CPE.
Protection Requirements
CPE should be protected against overvoltages that can exceed 800 V and against surge
currents up to 100 A. In Figure 3.1 through Figure 3.6, SIDACtor devices were chosen
because their associated peak pulse current (IPP) rating is sufficient to withstand the
lightning immunity test of TIA-968 (formerly known as FCC Part 68) without the additional
use of series line impedance. Likewise, the fuse shown in Figure 3.1 through Figure 3.6
was chosen because the amps2time (I2t) rating is sufficient to withstand the lightning
immunity tests of TIA-968 without opening, but low enough to pass UL power cross
conditions.
The following regulatory requirements apply:
•
•
TIA-968 (formerly known as FCC Part 68)
UL 60950
All CPE intended for connection to the PSTN must be registered in compliance with
TIA-968. Also, because the National Electric Code mandates that equipment intended for
connection to the telephone network be listed for that purpose, consideration should be
given to certifying equipment with an approved safety lab such as Underwriters
Laboratories.
CPE Reference Circuits
Figure 3.1 through Figure 3.6 show examples of interface circuits which meet all applicable
regulatory requirements for CPE. The P3100SB and P3100EB are used in these circuits
because the peak off-state voltage (VDRM) is greater than the potential of a Type B ringer
superimposed on a POTS (plain old telephone service) battery.
150 VRMSꢀꢁ2 + 56.6 VPK = 268.8 VPK
Note that the circuits shown in Figure 3.1 through Figure 3.6 provide an operational solution
for TIA-968 (formerly known as FCC Part 68). However TIA-968 allows CPE designs to
pass non-operationally as well.
For a non-operational solution, coordinate the IPP rating of the SIDACtor device and the I2t
rating of the fuse so that (1) both will withstand the Type B surge, and (2) during the Type A
surge, the fuse will open. (See Table 5.1, Surge Rating Correlation to Fuse Rating on page
5-8.)
Note: For alternative line interface protection circuits, see "Regulatory Compliant Solutions"
on page 4-34.

High Speed Transmission Equipment
High Speed Transmission Equipment
High speed transmission equipment encompasses a broad range of transmission protocols
such as T1/E1, xDSL, and ISDN. Transmission equipment is located at the central office,
customer premises, and remote locations.
Protection Requirements
Transmission equipment should be protected against overvoltages that can exceed 2500 V
and surge currents up to 500 A. In Figure 3.7 through Figure 3.17, SIDACtor devices were
chosen because their associated peak pulse current (IPP) rating is sufficient to withstand the
lightning immunity tests of GR 1089 without the additional use of series line impedance.
Likewise, the fuse shown in Figure 3.7 through Figure 3.17 was chosen because the
amps2time (I2t) rating is sufficient to withstand the lightning immunity tests of GR 1089, but
low enough to pass GR 1089 current limiting protector test and power cross conditions
(both first and second levels).
The following regulatory requirements apply:
•
•
•
•
TIA-968 (formerly known as FCC Part 68)
GR 1089-CORE
ITU-T K.20/K.21
UL 60950
Most transmission equipment sold in the US must adhere to GR 1089. For Europe and
other regions, ITU-T K.20/K.21 is typically the recognized standard.
ADSL Circuit Protection
Asymmetric Digital Subscriber Lines (ADSLs) employ transmission rates up to 6.144 Mbps
from the Central Office Terminal (COT) to the Remote Terminal (RT) and up to 640 kbps
from the RT to the COT at distances up to 12,000 feet. (Figure 3.7)

Longitudinal protection was not used at either the ADSL Transceiver Unit – Central Office
(ATU-C) interface or the ADSL Transceiver Unit – Remote (ATU-R) interface due to the
absence of earth ground connections. (Figure 3.8) In both instances, the P3500SC MC
SIDACtor device and the F1250T TeleLink fuse provide metallic protection. For ATUs not
isolated from earth ground, reference the HDSL protection topology.

The P3500SC MC SIDACtor device and F1250T TeleLink fuse were chosen to protect the
ATUs because both components meet GR 1089 surge immunity requirements without the
use of additional series resistance. Although the P3100 series SIDACtor device may be
used to meet current ANSI specifications, Teccor recommends the P3500 series to avoid
interference with the 20 VP-P x DSL signal on a 150 V rms ringing signal superimposed on a
56.5 V battery.
HDSL Circuit Protection
HDSL (High-bit Digital Subscriber Line) is a digital line technology that uses a 1.544 Mbps
(T1 equivalent) transmission rate for distances up to 12,000 feet, eliminating the need for
repeaters. The signaling levels are a maximum of ±2.5 V while loop powering is typically
under 190 V. (Figure 3.9)

Longitudinal protection is required at both the HDSL Transceiver Unit – Central Office
(HTU-C) and HDSL Transceiver Unit – Remote (HTU-R) interfaces because of the ground
connection used with loop powering. Two P2300SC MC SIDACtor devices provide
overvoltage protection and two F1250T TeleLink fuses (one on Tip, one on Ring) provide
overcurrent protection. (Figure 3.10) For the transceiver side of the coupling transformer,
additional overvoltage protection is provided by the P0080SA SIDACtor device. The
longitudinal protection on the primary coil of the transformer is an additional design
consideration for prevention of EMI coupling and ground loop issues.

Component Selection
The P2300SC MC SIDACtor device and the F1250T TeleLink fuse were chosen because
both components meet GR 1089 surge immunity requirements without the use of additional
series resistance. The P2300SC MC voltage rating was selected to ensure loop powering
up to 190 V. For loop powering greater than 190 V, consider the P2600SC MC. The
P0080SA MC SIDACtor device was chosen to eliminate any sneak voltages that may
appear below the voltage rating of the P2300SC MC.
ISDN Circuit Protection
Integrated Services Digital Network (ISDN) circuits require protection at the Network
Termination Layer 1 (NT1) U-interface and at the Terminating Equipment (TE) or
Terminating Adapter (TA) S/T interface. Signal levels at the U-interface are typically ±2.5 V;
however, with sealing currents and maintenance loop test (MLT) procedures, voltages
approaching 150 V rms can occur. (Figure 3.11)

varying signal voltages.
Pair Gain Circuit Protection
A digital pair gain system differs from an ISDN circuit in that ring detection, ring trip, ring
forward, and off-hook detection are carried within the 64 kbps bit stream for each channel
rather than using a separate D channel. The pair gain system also uses loop powering from
10 V up to 145 V with a typical maximum current of 75 mA. (Figure 3.13)

devices provide overvoltage protection and two F1250T TeleLink fuses (one on Tip, one on

is compliant with TIA-968 regulations, Section 4.4.5.2, “Connections with protection paths

The peak voltage for 120 V rms is 169.7 V. The minimum stand-off voltage for the P1800 is
170 V, therefore, the P1800SC MC will pass the test in Section 4.4.5.2 by not allowing
10 mA of current to flow during the application of this test voltage.
For the transceiver side of the coupling transformer, additional overvoltage protection is
shown in Figure 3.17 using the P0300SA SIDACtor device. When an earth ground
connection is not used, only metallic protection is required. Metallic protection is satisfied
using a single P0640SC MC SIDACtor device across Tip and Ring and a single F1250T
TeleLink fuse on either Tip or Ring.

Additional T1 Design Considerations
A T1 application can be TIA-968 approved as two different possible device types. An XD
device means an external CSU is used and the unit does not have to meet the
TIA-968 environmental test conditions, but it must connect only behind a separately
registered DE device. This XD equipment does not have to meet the T1 pulse template
requirements. If not classified as an XD device, then typically the application must adhere to
TIA-968 environmental test conditions.
T3 Protection
The capacitance across the pair of wires = (D1 || D2) + P0640EC/SC. The diode
capacitance is approximately (10 pF || 10 pF) 20 pF. Then adding the capacitive effect of
the P0640EC/SCMC, which is typically 60 pF, the total capacitance across the pair of wires
is approximately 15 pF. The MUR 1100E diodes are fast-switching diodes that will exhibit
this level of capacitance. MURS160T3 is a surface mount equivalent. (Figure 3.18)

Analog Line Cards
Given that line cards are highly susceptible to transient voltages, network hazards such as
lightning and power cross conditions pose a serious threat to equipment deployed at the
central office and in remote switching locations. To minimize this threat, adequate levels of
protection must be incorporated to ensure reliable operation and regulatory compliance.
Protection Requirements
When designing overvoltage protection for analog line cards, it is often necessary to
provide both on-hook (relay) and off-hook (SLIC) protection. This can be accomplished in
two stages, as shown in Figure 3.20.

following criteria to ensure proper coordination between the supply voltage (VREF) and the
maximum voltage rating of the SLIC to be protected.
V
DRM > VREF
VSꢀ?ꢀVSLIC Breakdown
This criterion can be accomplished in a variety of different ways. For applications using an
external ring generator and a fixed battery voltage, two P0641S_ SIDACtor devices
(P0721S_, P0901S_, or P1101S_ depending on the value of VREF) are used — one Tip to
Ground, one Ring to Ground. For applications using a ring-generating SLIC such as AMD’s
Am79R79, the B1XX0C_ or B1XX1U_ can be used.
IPP Selection
The I of the SIDACtor device must be greater than or equal to the maximum available
PP
surge current (IPK(available)) of the applicable regulatory requirements. Calculate the maximum
available surge current by dividing the peak surge voltage supplied by the voltage generator
(VPK) by the total circuit resistance (RTOTAL). The total circuit resistance is determined by
adding the source resistance (RS) of the surge generator to the series resistance in front of
the SIDACtor device on Tip and Ring (RTIP and RRING).
IPPꢀOꢀIPK(available)
IPK(available) = VPK / RTOTAL
For metallic surges:
R
TOTAL = RS + RTIP + RRING
For longitudinal surges:
TOTAL = RS + RTIP

RTOTAL = RS + RRING
Reference Diagrams
Figure 3.21 shows the use of Teccor’s “SC” rated SIDACtor devices and the F1250T
TeleLink fuse to meet the surge immunity requirements of GR 1089. Teccor’s P1200SC and
P2000SC, specifically designed to protect Agere Systems (formerly Lucent
Microelectronics) Line Card Access Switch (LCAS), provide on-hook protection. Two
P0641SCs provide off-hook protection. Any additional series resistance is absent because
the “C” series SIDACtor device and F1250T TeleLink fuse are designed to withstand
GR 1089 surges without the aid of additional components such as line feed resistors and
PTCs.

Figure 3.25 shows protection of a SLIC using 20 ꢂ series resistors on both Tip and Ring in
addition to Teccor’s Battrax (B1100CC) and a diode bridge (General Semiconductor part

The series resistance (a minimum of 20 ꢂ on Tip and 20 ꢂ on Ring) limits the simultaneous
surge currents of 100 A from Tip to Ground and 100 A from Ring to Ground (200 A total) to
within the surge current rating of the SA-rated SIDACtor device and Battrax. The diode
bridge shunts all positive voltages to Ground, and the B1100CC shunts all negative

In the application shown in Figure 3.26, each loop current would have to be limited to

CATV Equipment
CATV Equipment
As cable providers enter the local exchange market, protection of CATV (Community
Antenna TV) equipment becomes even more critical in order to ensure reliable operation of
equipment and uninterrupted service.
Protection Requirements
CATV line equipment should be able to withstand overvoltages that exceed 6000 V and
surge currents up to 5000 A. CATV station protectors should be able to withstand
overvoltages that exceed 5000 V and surge currents up to 1000 A. The SIDACtor devices
illustrated in Figure 3.32 through Figure 3.35 meet these requirements.

line amplifiers and power supplies versus using two SCRs and one SIDACtor device
(Figure 3.34). The P1900ME is used because the peak off-state voltage (VDRM) is well
above the peak voltage of the CATV power supply (90 VRMS ꢁ2), and the peak pulse current
rating (IPP) is 3000 A.

Primary Protection
Primary Protection
Primary telecommunications protectors must be deployed at points where exposed twisted
pairs enter an office building or residence. This requirement is mandated in North America
by the National Electric Code (NEC) to protect end users from the hazards associated with
lightning and power cross conditions.
Primary protection is provided by the local exchange carrier and can be segregated into
three distinct categories:
•
•
Station protection — typically associated with a single twisted pair
Building entrance protection — typically associated with multiple (25 or more) twisted
pair
•
Central office protection — typically associated with numerous twisted pair feeding into a
switch
Station protectors provide primary protection for a single-dwelling residence or office. The
station protector is located at the Network Interface Unit (NIU), which acts as the point of
demarcation, separating the operating company’s lines from the customer’s.
Building entrance protection is accomplished by installing a multi-line distribution panel with
integrated overvoltage protection. These panels are normally located where multiple twisted
pairs enter a building.
A five-pin protection module plugged into a Main Distribution Frame (MDF) provides Central
and Remote Office protection. Like station and building entrance protection, the MDF is
located where exposed cables enter the switching office.
Teccor also offers a full line of five-pin protectors. For further details, contact factory at
protectionsystems@teccor.com or +1 972-580-7777.
Protection Requirements
Station protectors must be able to withstand 300 A 10x1000 surge events. The building
entrance protectors and CO protectors must be able to withstand 100 A 10x1000 surge
events. Figure 3.36 shows building entrance protector and CO protector asymmetrical
solutions. Figure 3.37 shows building entrance protector and CO protector balanced
solutions.

Figure 3.36 and Figure 3.37 show different configurations used in primary protection. Note
that the peak off-state voltage (VDRM) of any device intended for use in primary protection
applications should be greater than the potential of a Type B ringer superimposed on a
POTS (plain old telephone service) battery.

Secondary Protection
Secondary Protection
Secondary protectors (stand alone units or integrated into strip protectors and UPSs) are
adjunct devices used to enhance the protection level of customer premise equipment
(CPE). Due to the inadequate level of protection designed into CPE, secondary protectors
often are required to prevent premature failure of equipment exposed to environmental
hazards (Figure 3.38).

Secondary protectors should be able to withstand overvoltages that can exceed 800 V and

associated peak pulse current (IPP) is sufficient to withstand the lightning immunity tests of
TIA-968 (formerly known as FCC Part 68) without the additional use of series line
impedance. Likewise, Figure 3.39 illustrates a fuse selected because the amps2time (I2t)
rating is sufficient to withstand the lightning immunity tests of TIA-968, but low enough to
pass UL power cross conditions.

150 VRMSꢀꢁ2 + 56.6 VPK = 268.8 VPK
Coordination between the station protector and the secondary protector occurs due to the
line impedance between the two devices. The line impedance helps ensure that the primary
protector will begin to conduct while the secondary protector limits any of the let-through
voltage to within the VS rating of the SIDACtor device.

Triac Protection
Triac Protection
Thyristors
Damage can occur to a thyristor if the thyristor’s repetitive peak off-state voltage is
exceeded. A thyristor’s repetitive peak off-state voltage may be exceeded due to dirty AC
power mains, inductive spikes, motor latch up, and so on.
Thyristor Reference Circuit
Figure 3.40 and Figure 3.41 show two different methods of protecting a triac. In Figure 3.40,
a SIDACtor device is connected from MT2 to the gate of the triac. When the voltage applied
to the triac exceeds the SIDACtor device’s VDRM, the SIDACtor device turns on, producing a
gate current which turns the triac on.

4 Regulatory
Requirements
Due to the enormous cost of interrupted service and failed network equipment, telephony
service providers have adopted various specifications to help regulate the reliability and
performance of the telecommunications products that they purchase. In Europe and much
of the Far East, the most common standards are ITU-T K.20 and K.21. In North America,
most operating companies base their requirements on GR 1089, TIA-968 (formerly known
as FCC Part 68), and UL 60950.
Note: This section is a paraphrase of existing documents and does not cover the listed

GR 1089–Core
GR 1089–Core
In the United States, the telecommunication network is primarily operated by the Regional
Bell Operating Companies (RBOC) who follow the standards set by GR 1089 or a derivative
thereof. GR 1089–Core (often referred to as GR 1089), “Electromagnetic Compatibility and
Electrical Safety Generic Criteria for Network Telecommunications Equipment,” covers the
requirements for telecommunications equipment connected to the outside world through
twisted pair. It also addresses the criteria for protection from lightning and AC power cross
disturbances.
Because twisted pair are metallic conductors exposed to lightning and AC power faults,
GR 1089 documents the requirements to be met by manufacturers of public switched
telephone network (PSTN) equipment to ensure safe and reliable operation.
The criteria for these standards are based on transient conditions at exposed sites, such as
remote facilities, central offices, and customers’ premises where operating companies
provide some type of primary voltage protection to limit transient voltages to 1000 V peak
for surge conditions and 600 V rms for power cross conditions.
All network equipment shall be listed by a Nationally Recognized Testing Laboratory
(NRTL) if the equipment is directly powered by Commercial AC. Network equipment located
on customer premises shall be listed by NRTL.
In conjunction with primary voltage protectors, operating companies also may incorporate
fuse links if there is the possibility of exposing the twisted pair to outside power lines. These
fuse links are equivalent to 24- or 26-gauge copper wire and are coordinated with the
current-carrying capacity of the voltage protector.
The last element of protection that may be provided by the operating company are current
limiters which, if provided, are found on the line side of the network equipment after the
primary voltage protection device. These current limiters typically come in the form of heat
coils and have a continuous rating of 350 mA.
Requirements
Equipment required to meet GR 1089 must be designed to pass:
•
•
•
Both First and Second Level Lightning Surge and AC Power Fault Tests
Current Limiter Test
Short Circuit Test
A minimum of three units are tested for each of the operating states in which the Equipment
Under Test (EUT) may be expected to function — idle, transmit, receive, on-hook, off-hook,
talking, dialing, ringing, and testing. Table 4.1 and Table 4.2 show test connections, and
Figure 4.1 shows the connection appearances.

GR 1089–Core
AC Power Fault Test is that the EUT may be damaged, but it may not become a fire,
fragmentation, or electrical safety hazard. Passing criteria for the Current Limiter Test is that
the EUT may be damaged but it may not exceed the acceptable time/current criteria (that is,
cannot cause the wiring simulator as shown in Figure 4.2 to open) nor become a fire,
fragmentation, or electrical safety hazard.
The indicator used in measuring fire, fragmentation, and electrical safety hazards is a
bleached, untreated cotton cheesecloth wrapped around the EUT. Compliance with testing
is determined by the absence of ignition, charring, and the ejection of molten material or
fragments.
First Level Lightning Surge Test
To pass the First Level Lightning Surge Test, the EUT must be undamaged and continue to
operate properly after the stress is applied. This is referred to as passing “operationally.”
Table 4.3 presents the conditions for the First Level inter-building criteria. Applicants have
the option to submit their equipment to meet surges 1, 2, 4, and 5 or surges 3, 4, and 5.

AC Power Fault Tests
Power companies and telephone operating companies often share telephone poles and
trenches; therefore, network equipment is often subjected to the voltages seen on power
lines. If direct contact between the telephone line and the primary power line occurs, the
operating company’s network equipment may see as much as 600 V rms for five seconds,
by which time the power company’s power system should clear itself. If direct contact
occurs with the secondary power line, voltages will be limited to 277 V rms; however, these
voltages may be seen indefinitely because the resultant current may be within the operating
range of the power system, and the power system will not reset itself.
Another risk involved with power lines is indirect contact. Because of the large magnetic
fields created by the currents in the power lines, large voltages may be induced upon phone
lines via electro-magnetic coupling. In this instance voltages should be limited to
1000 V peak and 600 V rms using primary protectors, while the current will be limited by the
current-carrying capacity of the 24-gauge wire.

Notes:
1. For EUT containing secondary voltage limiting and current limiting protectors, tests are to be performed at the indicated voltage(s)
and repeated at a reduced voltage and current just below the operating threshold of the secondary protectors.
2. Test 5 simulates a high impedance induction fault. For specific information, please contact Teccor Electronics.
3. Test conditions 6 through 9 are objective, not mandatory, requirements.
4. Sufficient time may be allowed between applications to preclude thermal accumulation.
Second Level AC Power Fault Criteria
Test conditions for the Second Level AC Power Fault Test are dependent on whether the
EUT is intended for customer premises equipment or non-customer premises equipment. In
both instances, although the EUT is not required to pass operationally, it may not become a
fire, fragmentation, or electrical safety hazard.
Second Level AC Power Fault Criteria for Non-customer Premises
Equipment
Table 4.7 presents test conditions for non-customer premises equipment. (Note that test
conditions 1, 3, and 4 may be omitted if the EUT has previously met UL 60950.) See
Figure 4.1 for test connection appearances.

4. Test 5 simulates a high impedance induction fault. Specific information regarding this test is available upon request.
5. These tests are repeated using a short-circuit value just below the operating threshold of the current limiting device, or, if the EUT
uses a fuse as current limiting protection, the fuse may be bypassed and the short circuit current available adjusted to 135% of the
fuse rating.
6. Intra-building, second level lower fault test uses test condition 1 only. The applied voltage is at 120 V rms only.
Second Level AC Power Fault for Customer Premises Equipment
For customer premises equipment, the EUT is tested to the conditions presented in
Table 4.8 and connected to a circuit equivalent to that shown in Figure 4.2. During this test,
the wiring simulator cannot open. For equipment that uses premises type of wiring, the
wiring simulator is a 1.6 A Type MDQ fuse from Bussman. For equipment that is connected
by cable, the wiring simulator is a piece of 26-gauge copper wire.

Current Limiting Protector Test
The purpose of the Current Limiting Protector Test, presented in Table 4.9, is to determine if
the EUT allows an excessive amount of current flow under power fault conditions. During
this test, the EUT is connected to a circuit equivalent to that shown in Figure 4.2 with a
1.6 A Type MDQ fuse from Bussman used as the wiring simulator. If the EUT draws enough
current to open the fuse, then the acceptable time/current criteria have not been met, and
external current limiting protectors must be specified for use with that equipment in the
manufacturer’s documentation.

Short-circuit Test
In addition to the AC Power Fault and Current Limiter Tests, equipment must also pass a
Short-circuit Test to comply with GR 1089. During this test, a short-circuit condition is
applied to the following Tip and Ring appearances for 30 minutes while the EUT is powered
and under operating conditions:
•
•
•
Tip-to-Ring, Tip-to-Ground with Ring open circuit
Ring-to-Ground with Tip open circuit
Tip- and Ring-to-Ground simultaneously for 30 minutes
At no time will the short circuit exceed 1 ꢂ. For equipment with more than one twisted pair,
the short circuit is applied to all twisted pair simultaneously. To comply with the short circuit
test, the EUT must function normally after the short-circuit condition is removed, and a fire
hazard may not be present. The equipment shall not require manual intervention to restore
service.

ITU-T K.20 and K.21
ITU-T K.20 and K.21
Although the International Telecommunication Union (ITU) does not have the authority to
legislate that organizations follow their recommendations, their standards are recognized
throughout Europe and the Far East.
ITU-T, the Telecommunication Standardization Sector of the ITU, developed fundamental
testing methods that cover various environmental conditions to help predict the survivability
of network and customer-based switching equipment. The testing methods cover the
following conditions:
•
Surges due to lightning strikes on or near twisted pair and plant equipment (excluding a
direct strike)
Short-term induction of AC voltage from adjacent power lines or railway systems
Direct contact between telecommunication lines and power lines (often referred to as
AC power cross)
•
•
Two ITU-T standards apply for most telecommunications equipment connected to the
network:
•
•
ITU-T K.20
ITU-T K.21
ITU-T K.20 is primarily for switching equipment powered by the central office; however, for
complex subscriber equipment, test administrators may choose either K.20 or K.21,
depending on which is deemed most appropriate.
Note: Both standards are intended to address equipment reliability versus equipment
safety. For specific concerns regarding equipment safety, research and follow
national standards for each country in which the equipment is intended for use.
K.21 covers telecommunication equipment installed in customer premises. Equipment
submitted under these requirements must meet one of two levels: basic or enhanced.
Guidelines for determining under which level the equipment under test (EUT) falls can be
found in ITU-T K.11, but note that the final authority rests with the test administrator.
ITU-T K.44 describes the test conditions used in K.20 and K.21.
ITU-T defines the following acceptance criteria:
•
Criterion A states that equipment shall withstand the test without damage and shall
operate properly after the test. It is not required to operate correctly during the test.
Criterion B states that a fire hazard shall not occur as a result of the tests. Any damage
shall be confined to a small part of the equipment.
•
Table 4.10 shows the lightning surge test conditions for ITU K.20. Figure 4.3 shows the
connection schematic for the lightning surge tests. Table 4.11 shows the power cross test
conditions for ITU K.20. Figure 4.4 shows the connection schematic for the power cross
tests. Table 4.12 and Table 4.13 show the same test conditions respectively for ITU K.21.

TIA-968 (formerly known as FCC Part 68)
TIA-968 (formerly known as FCC Part 68)
TIA-968 applies to all terminal equipment connected to the Public Switched Telephone
Network (PSTN) and holds the “rule of law” by congressional order.
The purpose of TIA-968 is to provide a set of uniform standards to protect the telephone
network from any damage or interference caused by the connection of terminal equipment.
This standard includes environmental simulations such as vibration tests, temperature and
humidity cycling, drop tests and tests for hazardous voltages and currents, as well as tests
for signal power levels, line balance, on-hook impedance, and billing protection. All these
standards must be met before and after the environmental tests are applied.
Overvoltage Test
TIA-968 compliant equipment must undergo an overvoltage test that includes a Type A and
Type B Metallic Voltage Surge and a Type A and Type B Longitudinal Voltage Surge. These
surges are part of the environmental simulation, and although a provision does allow the
EUT to reach an open circuit failure mode during the Type A tests, failures must:
1. Arise from an intentional design that will cause the phone to be either disconnected from
the public network or repaired rapidly
2. Be designed so that it is substantially apparent to the end user that the terminal
equipment is not operable
A common example of an acceptable failure would be an open circuit due to an open
connection on either Tip or Ring.
For Type B surges, equipment protection circuitry is not allowed to fail. The EUT must be
designed to withstand Type B surges and continue to function in all operational states.
Metallic Voltage Surge
The Type A and Type B Metallic Voltage Surges are applied in both the positive and
negative polarity across Tip and Ring during all operational states (on-hook, off-hook,
ringing, and so on). The Type A surge is an 800 V, 100 A peak surge while the Type B
surge is a 1000 V, 25 A peak surge, as presented in Table 4.14.

For Type A surges, the EUT may pass either “operationally” or “non-operationally.”
For Type B surges, the EUT must pass “operationally.”
The peak current for the Type A longitudinal surge is the total available current from the surge generator.
The peak current for the Type B longitudinal surge is the current supplied to each conductor.

TIA-968 (formerly known as FCC Part 68)
Longitudinal Voltage Surge
The Type A and Type B Longitudinal Voltage Surges are applied in both positive and
negative polarity during all operational states. The Type A surge is a 1500 V, 200 A peak
surge applied to the EUT with Tip and Ring tied together with respect to Ground. The
Type B Longitudinal Voltage Surge is a simultaneous surge in which 1500 V and 37.5 A are
applied concurrently to Tip with respect to Ground and Ring with respect to Ground, as
presented in Table 4.14.
Note: Type B surge requirements guarantee only a minimum level of surge protection. For
long term reliability of terminal equipment, consideration should be given to
complying with Type A surges operationally.
On-hook Impedance Limitations
Another important aspect of TIA-968 is on-hook impedance, which is affected by transient
protection. On-hook impedance is analogous to the leakage current between Tip and Ring,
and Tip, Ring, and Ground conductors during various on-hook conditions. "On-hook
Impedance Measurements" (next paragraph) outlines criteria for on-hook impedance and is
listed as part of the Ringer Equivalent Number (REN). The REN is the largest of the unitless
quotients not greater than five; the rating is specified as the actual quotient followed by the
letter of the ringer classification (for example, 2B).
On-hook Impedance Measurements
On-hook impedance measurements are made between Tip and Ring and between Tip and
Ground and Ring and Ground. For all DC voltages up to and including 100 V, the DC
resistance measured must be greater than 5 Mꢂ. For all DC voltages between 100 V and
200 V, the DC resistance must be greater than 30 kꢂ. The REN values are then determined
by dividing 25 Mꢂ by the minimum measured resistance up to 100 V and by dividing
150 kꢂ by the minimum measured resistance between 100 V and 200 V.
On-hook impedance is also measured during the application of a simulated ringing signal.
This consists of a 40 V rms through 150 V rms ringer signal at frequencies ranging from
15.3 Hz to 68 Hz superimposed on a 56.5 V dc for a class “B” ringer. During this test, the
total DC current may not exceed 3 mA. In addition, the minimum DC resistance measured
between Tip and Ring must be greater than 1600 ꢂ, while the DC resistance measured
between the Tip and Ring conductors and Ground must be greater than 100 kꢂ. The REN
values for the simulated ringing test are determined by dividing the maximum DC current
flowing between Tip and Ring by 0.6 mA, and by dividing 8000 ꢂ by the minimum
impedance value measured.

UL 60950 3rd Edition (formerly UL 1950, 3rd edition)
UL 60950 3rd Edition
(formerly UL 1950, 3rd edition)
After the divestiture of the AT&T/Bell system, the National Electric Code (NEC)
implemented Article 800-4, which mandates that “all equipment intended for connection to
the public telephone network be listed for that purpose” in order to ensure electrical safety.
A manufacturer can meet this requirement by listing their product with Underwriters
Laboratories under UL 60950 (based on IEC 60950, 3rd edition).
NEC requires all telecommunication wiring that enters a building to pass through a primary
protector, which is designed to limit AC transients in excess of 600 V rms. These transients
are due to the fact that telephone lines run in close proximity to AC power lines. Most
telecommunication equipment uses a secondary overvoltage protector such as the
SIDACtor device. The secondary devices typically limit transients in excess of 350 V rms.
Therefore, a potentially dangerous condition exists because of the voltage threshold
difference of the primary protector and the secondary protector. To minimize this danger,
compliance with UL 60950 overvoltage tests is required.
UL 60950 covers equipment with a rated voltage (primary power voltage) not exceeding
600 V and equipment designed to be installed in accordance with NEC NFPA 70. This
standard does not apply to air-conditioning equipment, fire detection equipment, power
supply systems, or transformers.
The effective date of UL 60950 allows new products submitted through April 1, 2003 to be
evaluated using the requirements of either UL 60950 or UL 1950, 3rd edition. After April 1,
2003, all new product submittals must be evaluated using only UL 60950.
Products certified by UL to requirements of UL 1459 prior to April 1, 2000 may continue to
be certified without further reinvestigation until April 1, 2005, provided no significant
changes or revisions are made to the products. Products certified by UL to requirements of
UL 1950 3rd edition prior to April 1, 2003 may continue to be certified without further
reinvestigation until April 1, 2005.
In order to have the UL Mark applied after April 1, 2005, all products, including those
previously certified by UL, must comply with UL 60950.
UL 69050 is intended to prevent injury or harm due to electrical shock, energy hazards, fire,
heat hazards, mechanical hazards, radiation hazards, and chemical hazards.
It defines three classes of equipment:
•
•
•
Class 1 — protection achieved by basic insulation
Class 2 — protection achieved by double or reinforced insulation
Class 3 — protection relying upon supply from SELV circuits (voltages up to 40 V peak
or 60 V dc)
UL 60950 also defines five categories of insulation:
•
•
•
•
•
Functional
Basic
Supplementary
Reinforced
Double

UL 60950 3rd Edition (formerly UL 1950, 3rd edition)
UL 60950 Terminology
The following definitions assist in understanding UL 60950:
SELV
Secondary circuit whose voltage values do not exceed a safe value
(voltage less than hazardous levels of 42.4 V peak or 60 V dc)
TNV
Telecommunication Network Voltage (a secondary circuit)
O SELV but with exposure to surges
TNV3
TNV2
TNV1
O SELV but without exposure to surges
? SELV with exposure to surges
Creepage distance is the shortest distance between two conductors, measured along the
surface of the insulation. DC voltages shall be included in determining the working voltage
for creepage distances. (The peak value of any superimposed ripple or short disturbances,
such as cadenced ringing signals, shall be ignored.)
Clearance distance is the shortest distance between two conductive parts or between a
conductive part and the outer surface of the enclosure measured through air. DC voltages
and the peak value of any superimposed ripple shall be included in determining the working
voltage for clearance distances.
Creepage and clearance distances are also subject to the pollution degree of the
equipment:
•
Pollution degree 1 — components and assemblies that are sealed to prevent ingress of
dust and moisture
Pollution degree 2 — generally applicable to equipment covered by UL 60950
Pollution degree 3 — equipment is subject to conductive pollution or to dry non-
conductive pollution, which could become conductive due to expected condensation.
•
•
To ensure safe operating conditions of the equipment, UL 60950 focuses on the insulation
rating of the circuit(s) under consideration. Table 4.15 and Table 4.16 indicate the required
creepage and clearance distances depending on material group, pollution degree, working
voltage, and maximum transient voltage in the secondary circuit. For a typical
telecommunication application with a working voltage of 200 V, pollution degree 2, material
group IIIb, the creepage distance is 2 mm. The clearance distance is 2 mm for reinforced
insulation.

UL 60950 3rd Edition (formerly UL 1950, 3rd edition)
The application must meet the creepage and clearance distances and electric strength of
Section 5.3.2 of UL 60950 for functional insulation. The electric strength test (Table 5B of
UL 60950) lists 1 kV to 1.5 kV as the test voltages for functional and supplementary grade
of insulation and 2 kV to 3 kV for reinforced grade of insulation.
Separation requirements are tested (Section 6.2.2.1 of UL 60950) by applying an impulse
test and an electric strength test:
•
Impulse test allows for the SIDACtor device to turn on (either a 10x700 2.5 kV 62.5 A or
1 kV 37.5 A 10 times with 60-second rest period).
Electric strength test allows the SIDACtor device to be removed (60 Hz at rated voltage
for 60 seconds).
•
These are applied between Ground and all Tip and Rings connected together, and/or
between Ground and all conductors intended to be connected to other equipment
connected together.
Basic insulation is not required if all the following conditions are met:
•
•
SELV, TNV1 circuit is connected to the protective earth.
Installation procedures specify that protective earth terminal shall have a permanent
connection to earth.
•
Any TNV2 or TNV3 circuit with an external port connection intended to receive signals in
excess of SELV (60 V dc or 50 V peak) will have the maximum normal expected
operating voltage applied to it for up to 30 minutes without deterioration. (If no maximum
normal specification exists then 120 V 100 mA 60 Hz is applied.)
(In other words, if a permanent Ground connection is made, then creepage distances may
not be required.)
Any surge suppressor that bridges the insulation (connects to Ground) shall have a
minimum DC turn on voltage of 1.6 times the rated voltage UNLESS one of the following
occurs (Section 6.1.2.2 of UL 60950):
•
•
•
Equipment is permanently connected or uses an industrial plug and socket-outlet.
Equipment is installed by service personnel.
Equipment has provision for a permanently connected protective earth.
ANNEX C of UL 60950 covers transformers.
The secondary side is loaded for maximum heating effect. The maximum working voltage is
applied to the primary. The DC peak value of any superimposed ripple shall be included.
The permitted temperature limits for the windings depend on the classification:
•
•
•
•
•
Class A limit is 150 °C.
Class B limit is 175 °C.
Class E limit is 165 °C.
Class F limit is 190 °C.
Class H limit is 210 °C.

flaming drops, or glowing particles that could be emitted by the equipment under fault conditions. Fire enclosure
construction is covered in Section 4.4.6 of UL 60950. Spacing applies to parts in the TNV circuits that might ignite under
overvoltage conditions. Spacing requirements mandate that parts be separated from internal materials of flammability
class V-2 or lower, by at least 25 mm of air or a barrier material of flammability class V-1 or better. Parts also should be
separated from openings in the top or sides of the enclosure by at least 25 mm of air or a material barrier.
6. Test Condition 2 is not required for equipment with 1.3 A limiting.
7. Test Conditions 3 and 4 are not required for connections limited to outside cable less than 1,000 m.

Overvoltage Test Procedures
Use the following criteria when applying the overvoltage tests presented in Table 4.17:
1. Test Set-up — Equipment is to be mounted as it is intended to be used. Tests may be
conducted on either the equipment as an assembly, individual subassemblies, or a
partial assembly containing those components which may be exposed to an overvoltage
condition.
2. Indicators — Before testing, two single pieces of cheesecloth are to be wrapped tightly
around the assembly, subassembly, or partial assembly. The cheesecloth acts as an
indicator for conditions that may result in fire.
3. Line Cords — Equipment with a removable telecommunications line cord is to be
connected to the test circuit with a line cord having 0.4 mm (26 AWG) or larger copper
wire conductors and not more than 1 ꢂ total resistance.
4. Functional Circuitry — UL mandates that functional circuitry must be used for each
overvoltage test conducted. This allows repair or replacement of damaged circuitry
before subsequent testing. Alternatively, separate samples may be used for each test.
5. Wiring Simulators — A wiring simulator is used to indicate whether the maximum I2t
imposed upon telecommunications wiring has been exceeded. For Tests 1 and 5, a
wiring simulator is to be used unless the equipment is specified for use with a suitable
secondary protector or a secondary protector simulator. The wiring simulator can consist
of one of the following:
a. 50mm length of 0.2 mm (32 AWG) bare or enameled solid copper wire (for test
condition 1)
b. Bussman Mfg. Co. Type MDL-2A fuse (for test condition 1)
c. 300 mm length of 0.4 mm (26 AWG) solid copper wire which connects to a
representative installation (includes wiring an connectors)
[This option is used when the manufacturer specifies the complete installation from
the network interface to the equipment.]
d. Current probe used with a 300 mm length of 0.5 mm (24 AWG) copper wire (for test
condition 1)

SIDACtor Data Book and Design Guide
®
UL 60950 3rd Edition (formerly UL 1950, 3rd edition)
Note: Test conditions 2, 3, and 4 do not require the use of a wiring simulator or a secondary
protector simulator. Any secondary protection simulators used in Tests 1 and 5
should be similar to the test fuse used in UL 497A, “Standard for Secondary
Protectors for Communications Circuits.”
Overvoltage Test Compliance
Equipment is deemed compliant if each of the following conditions are met during test:
•
Absence of ignition or charring of the cheesecloth indicator
(Charring is deemed to have occurred when the threads are reduced to char by a
glowing or flaming condition.)
Wiring simulator does not open during test condition 1 or 5
For test condition 1, presented in Table 4.17, the integral I2t measured with a current
probe is less than 100 A2s.
•
•
After completion of the overvoltage tests, equipment must comply with either the Dielectric
Voltage-withstand Test requirements with all components in place or the Leakage Current
Test requirements.
Special Considerations Regarding the SIDACtor Device and UL 60950
The epoxy used for SIDACtor devices is UL recognized and the encapsulated body passes
UL 94V-0 requirements for flammability.
The only specific requirements of UL 60950 that pertain to the SIDACtor device itself are
the impulse test and the mandate that components be UL recognized. All other UL 60950
requirements pertain to the equipment being evaluated.

UL 497 Series of Safety Standards
The UL 497 series is a family of three safety standards that provides requirements for
protection devices used in low-voltage circuits.
•
UL 497 addresses requirements for primary protectors used in paired communications
circuits.
•
UL 497A covers secondary protectors for use in single or multiple pair-type
communications circuits.
•
•
UL 497B addresses protectors used in data communication and fire alarm circuits.
UL 497C addresses protectors for coaxial circuits.
The focus of UL 497 is to ensure that paired communication circuit protectors do not
become a fire or safety hazard. The requirements in UL 497 cover any protector that is
designed for paired communications circuits and is employed in accordance with Article 800
of the National Electric Code. The protectors covered in UL 497 include solid state primary
and station protectors. These circuit protectors are intended to protect equipment, wiring,
and service personnel against the effects of excessive voltage potential and currents in the
telephone lines caused by lightning, power cross, power induction, and rises in Ground
potential.

Performance Tests
Key performance tests which concern overvoltage protectors are detailed in the arrestor
test section. Specific requirements are:
•
Breakdown Voltage Measurement — Arrestors are to be tested in the protector blocks or
panels in which they are intended to be employed. Arrestors are required to break down
within ±25% of the manufacturer’s specified breakdown rating. In no case shall the
breakdown voltage exceed 750 V peak when subjected to the strike voltage test shown
in Figure 4.8. At no time during this test will the supply voltage be increased at a rate
greater than 2000 V/µs.
•
•
Impulse Spark-over Voltage Measurement — The arrestor must break down at less than
1000 V peak when subjected to a single impulse potential. Arrestors are to be tested in
each polarity with a rate of voltage rise of 100 V/µs, ±10%.
Abnormal Operation — Single pair fuseless arrestors must be able to simultaneously
carry 30 A rms at 480 V rms for 15 minutes without becoming a fire hazard. A fire hazard
is determined by mounting the arrestor on a vertical soft wood surface and covering the
unit with cheesecloth. Any charring or burning of the cheesecloth results in test failure.
During this test, although the arrestors may short, they must not have an impulse spark-
overvoltage or DC breakdown voltage greater than 1500 V peak.
•
•
Discharge Test — Protectors must comply with the strike voltage requirements after
being subjected to five successive discharges from a 2 µF capacitor charged to
1000 V dc. (Figure 4.9).
Repeated Discharge Test — The arrestor must continue to break down at or below its
maximum rated breakdown voltage after being subjected to 500 discharges from a
0.001 µF capacitor charged to a potential of 10,000 V dc. The interval between pulses is
five seconds. Arrestors are to be tested in each polarity, and it is acceptable for the
protector to short circuit following the discharge testing. (Figure 4.9)

Performance Tests
The following key performance tests relate to overvoltage protection of the secondary
protectors:
1. Impulse Voltage Measurement Test — Secondary protectors must break down within
±25% of the manufacturer’s breakdown rating when tested in each polarity with a rate of
voltage rise of 100 V/µs, ±10%. Note that the manufacturer may assign separate
breakdown voltage ratings for the Breakdown Voltage Measurement Test. This
requirement only applies to secondary protectors that connect between Tip and Ring of
the telephone loop.
2. Breakdown Voltage Measurement Test — Secondary protectors must break down within
±25% of the manufacturer’s breakdown rating when tested in each polarity with a rate of
voltage rise no greater than 2000 V/s. The secondary protector is to be mounted in
accordance with the manufacturer’s installation instructions and then subjected to the
test circuit shown in Figure 4.10. This requirement applies only to secondary protectors
connected between Tip and Ring or Tip/Ring and Ground of the telephone loop.
3. Overvoltage Test — Secondary protectors must limit current and extinguish or open the
telephone loop without loss of its overvoltage protector, indication of fire risk, or electric
shock. Upon completion of this test, samples must comply with the Dielectric Voltage-
withstand Test.
The overvoltage test is used to determine the effects on secondary protectors and is shown
in Table 4.18. Test connections are shown in Figure 4.11.
Test Compliance
Compliance with the overvoltage test is determined by meeting the following criteria:
•
•
•
Cheesecloth indicator may not be either charred or ignited
Wiring simulator (1.6 A Type MDQ fuse or 26 AWG line cord) may not be interrupted
Protector meets the applicable dielectric voltage withstand requirements after the
completion of the overvoltage tests

Regulatory Compliant Solutions
Regulatory Compliant Solutions
When determining the most appropriate solution to meet the lightning and AC power fault
conditions for regulatory requirements, coordination is essential between the SIDACtor
device, fuse, and any series impedance that may be used.
Figure 4.14 through Figure 4.19 show templates in which this coordination is considered for
the most cost effective and reliable solutions available. For exact design criteria and
information regarding the applicable regulatory requirements, refer to the SIDACtor device
and fuse selection criteria in this Section 4, “Regulatory Requirements”, and in Section 5,
“Technical Notes”.
GR 1089 and ITU-T K.20 and K.21
Figure 4.14 and Figure 4.15 show line interface protection circuits to meet GR 1089 surge
immunity requirements without the additional use of series resistance. Use the “C” series
SIDACtor device and F1250T to meet GR 1089 surge immunity requirements. Use the
“A” series SIDACtor device and F0500T to meet ITU-T K.20 and K.21 basic surge immunity
requirements without the additional use of resistance.
The enhanced surge immunity requirements of ITU K.20 and K.21 require the use of “C”
rated SIDACtor devices if no series resistor is used.

Because equipment that is tested to TIA-968 (formerly known as FCC Part 68)
specifications is also generally tested to UL 60950 specifications, it is easiest to look at a
solution that meets both FCC and UL requirements simultaneously.

for TIA-968, TIA-968 allows telecommunications equipment to pass Type A surges non-
operationally as well. For non-operational TIA-968 solutions, coordinate the IPP rating of the
SIDACtor device and the I2t rating of the fuse so that both will withstand the TIA-968 Type B
surge, but that during the Type A surge the fuse will open.

Surge Waveforms for Various Standards
Surge Waveforms for Various Standards
TIA-968 now replaces FCC Part 68, except for hearing aid compatibility (HAC), volume
control, and indoor cabling. This has become harmonized with Canadian requirements.
Various countries around the world have adopted this regulation.
GR 1089 is a standard generally supported by the US Regional Bell Operating Companies
(RBOC). It is updated by Telcordia Technology (formerly Bellcore). The RBOC typically
requires compliance with GR 1089 for any of their telecom purchases.
ITU is a specialized agency of the UN devoted to international harmonization. Most
European countries recognize the ITU standards.
CNET is the Centre National d’etudes de Telecommunications, a French organization.
VDE is the Verband Deutsher Elektrotechniker, a Federation of German electrical
engineers. VDE is very similar to the IEEE (Institute of Electrical and Electronics Engineers)
but is national in scope rather than global.
ANSI is the American National Standards Institute, which is a non-government organization.
The British equivalent to this is BSI.
IEC is the International Electrotechnical Commission, a result of Europe’s move toward a
single market structure and its drive to formalize and harmonize member countries’
requirements.
FTZ R12 is a German specification.

Construction and Operation
Construction and Operation
SIDACtor devices are thyristor devices used to protect sensitive circuits from electrical
disturbances caused by lightning-induced surges, inductive-coupled spikes, and AC power
cross conditions. The unique structure and characteristics of the thyristor are used to create
an overvoltage protection device with precise and repeatable turn-on characteristics with
low voltage overshoot and high surge current capabilities.
Key Parameters
Key parameters for SIDACtor devices are VDRM, IDRM, VS, IH, and VT, as shown in Figure 5.1.
V
DRM is the repetitive peak off-state voltage rating of the device (also known as stand-off
voltage) and is the continuous peak combination of AC and DC voltage that may be applied
to the SIDACtor device in its off-state condition. IDRM is the maximum value of leakage
current that results from the application of VDRM. Switching voltage (VS) is the maximum
voltage that subsequent components may be subjected to during a fast-rising (100 V/µs)
overvoltage condition. Holding current (IH) is the minimum current required to maintain the
device in the on state. On-state voltage (VT) is the maximum voltage across the device
during full conduction.

Operation
The SIDACtor device operates much like a switch. In the off state, the device exhibits
leakage currents (IDRM) less than 5 µA, making it invisible to the circuit it is protecting. As a
transient voltage exceeds the SIDACtor device’s VDRM, the device begins to enter its
protective mode with characteristics similar to an avalanche diode. When supplied with
enough current (IS), the SIDACtor device switches to an on state, shunting the surge from
the circuit it is protecting. While in the on state, the SIDACtor device is able to sink large

Construction and Operation
amounts of current because of the low voltage drop (VT) across the device. Once the
current flowing through the device is either interrupted or falls below a minimum holding
current (IH), the SIDACtor resets, returning to its off state. If the IPP rating is exceeded, the
SIDACtor device typically becomes a permanent short circuit.
Physics
The SIDACtor device is a semiconductor device which is characterized as having four
layers of alternating conductivity: PNPN. (Figure 5.2) The four layers include an emitter
layer, an upper base layer, a mid-region layer, and a lower base layer. The emitter is
sometimes referred to as a cathode region, with the lower base layer being referred to as
an anode region.
As the voltage across the SIDACtor device increases and exceeds the device’s VDRM, the
electric field across the center junction reaches a value sufficient to cause avalanche
multiplication. As avalanche multiplication occurs, the impedance of the device begins to
decrease, and current flow begins to increase until the SIDACtor device’s current gain
exceeds unity. Once unity is exceeded, the SIDACtor device switches from a high
impedance (measured at VS) to a low impedance (measured at VT) until the current flowing
through the device is reduced below its holding current (IH).

SIDACtor Device Selection Criteria
SIDACtor Device Selection Criteria
When selecting a SIDACtor device, the following criteria should be used:
Off-state Voltage (VDRM
)
The V
of the SIDACtor device must be greater than the maximum operating voltage of
DRM
the circuit that the SIDACtor device is protecting.
Example 1:
For a POTS (Plain Old Telephone Service) application, convert the maximum operating
Ring voltage (150 V rms) to a peak voltage, and add the maximum DC bias of the central
office battery:
150 VRMS ꢁ2 + 56.6 VPK = 268.8 VPK
ꢃꢀVDRM > 268.8 V
Example 2:
For an ISDN application, add the maximum voltage of the DC power supply to the
maximum voltage of the transmission signal (for U.S. applications, the U-interface will not
have a DC voltage, but European ISDN applications may):
150 VPK + 3 VPK = 153 VPK
ꢃꢀVDRM > 153 V
Switching Voltage (VS)
The V of the SIDACtor device should be equal to or less than the instantaneous peak
S
voltage rating of the component it is protecting.
Example 1:
VS ? VRelay Breakdown
Example 2:
VS ? SLIC VPK
Peak Pulse Current (IPP)
For circuits that do not require additional series resistance, the surge current rating (IPP) of
the SIDACtor device should be greater than or equal to the surge currents associated with
the lightning immunity tests of the applicable regulatory requirement (IPK):
IPP O IPK
For circuits that use additional series resistance, the surge current rating (IPP) of the
SIDACtor device should be greater than or equal to the available surge currents associated
with the lightning immunity tests of the applicable regulatory requirement (IPK(available)):
IPP O IPK(available)

SIDACtor Data Book and Design Guide
SIDACtor Device Selection Criteria
The maximum available surge current is calculated by dividing the peak surge voltage (VPK
by the total circuit resistance (RTOTAL):
)
IPK(available) = VPK/RTOTAL
For longitudinal surges (Tip-Ground, Ring-Ground), RTOTAL is calculated for both Tip and
Ring:
R
SOURCE = VPK/IPK
RTOTAL = RTIP + RSOURCE
RTOTAL = RRING + RSOURCE
For metallic surges (Tip-Ring):
RSOURCE = VPK/IPK
RTOTAL = RTIP + RRING + RSOURCE
Example 1:
A modem manufacturer must pass the Type A surge requirement of TIA-968 (formerly
known as FCC Part 68) without any series resistance.
I
PK = 100 A, 10x560 µs
IPP O 100 A, 10x560 µs
Therefore, either a “B” rated or “C” rated SIDACtor device would be selected.
Example 2:
A line card manufacturer must pass the surge requirements of GR 1089 with 30 ꢂ on Tip
and 30 ꢂ on Ring.
I
PK = 100 A, 10x1000 µs
PK = 1000 V
SOURCE = VPK/IPK = 10 ꢂ

R
RTOTAL = RSOURCE RTIP = 40 ꢂ
+
IPK (available) = VPK/RTOTAL = 1000 V/40 ꢂ
ꢃ IPP O 25 A
Holding Current (IH)
Because TIA-968 4.4.1.7.3 specifies that registered terminal equipment not exceed
140 mA dc per conductor under short-circuit conditions, the holding current of the SIDACtor
device is set at 150 mA.
For specific design criteria, the holding current (IH) of the SIDACtor device must be greater
than the DC current that can be supplied during an operational and short circuit condition.

Assuming that the critical point of insertion loss is 70% of the original signal value, the
SIDACtor device can be used in most applications with transmission speeds up to 30 MHz.

Fuse Selection Criteria
Fuse Selection Criteria
A fuse can be relied upon to operate safely at its rated current, at or below its rated voltage.
This voltage rating is covered by the National Electric Code (NEC) regulations and is a
requirement of UL as protection against fire risk. The standard voltage ratings used by fuse
manufacturers for most small dimension fuses are 32 V, 63 V, 125 V, 250 V, and 600 V.
Fuses are not sensitive to changes in voltage; however, they are sensitive to changes in
current. The fuse will maintain “steady-state” operation from zero volts to the maximum
voltage rating. It is not until the fuse element melts and internal arcing occurs, that circuit
voltage and available power become an issue. The interrupt rating of the fuse addresses
this issue. Specifically, the voltage rating determines the ability of the fuse to suppress
internal arcing that occurs after the fuse link melts.
For telecommunication applications, a voltage rating of 250 V is chosen because of the
possibility of power line crosses. A three-phase voltage line will have voltage values up to
220 V. It is desirable for the voltage rating of the fuse to exceed this possible power cross
event.
UL 60950 has a power cross test condition that requires a fuse to have an interrupt rating of
40 A at 600 V. GR 1089 contains a power cross test condition that requires a fuse to have
an interrupt rating of 60 A at 600 V. A 125 V-rated part will not meet this requirement.
A 250 V part with special design consideration, such as Teccor’s F1250T TeleLink
fuse, does meet this requirement.
Because fuses are rated in terms of continuous voltage and current-carrying capacity, it is
often difficult to translate this information in terms of peak pulse current ratings. To simplify
this process, Table 5.1 shows the surge rating correlation to fuse rating.

a high off-state impedance when biased with a voltage less than their respective blocking
voltages.
SIDACtor devices
A SIDACtor device is a PNPN device that can be thought of as a TVS diode with a gate.
Upon exceeding its peak off-state voltage (VDRM), a SIDACtor device will clamp a transient
voltage to within the device’s switching voltage (VS) rating. Then, once the current flowing
through the SIDACtor device exceeds its switching current, the device will crowbar and
simulate a short-circuit condition. When the current flowing through the SIDACtor device is
less than the device’s holding current (IH), the SIDACtor device will reset and return to its
high off-state impedance.
Advantages
Advantages of the SIDACtor device include its fast response time (Figure 5.3), stable
electrical characteristics, long term reliability, and low capacitance. Also, because the
SIDACtor device is a crowbar device, it cannot be damaged by voltage and it has extremely
high surge current ratings.
Restrictions
Because the SIDACtor device is a crowbar device, it cannot be used directly across the
AC line; it must be placed behind a load. Failing to do so will result in exceeding the
SIDACtor device’s surge current rating, which may cause the device to enter a permanent
short-circuit condition.
Applications
Although found in other applications, SIDACtor devices are primarily used as the principle
overvoltage protector in telecommunications and data communications circuits. For
applications outside this realm, follow the design criteria in "SIDACtor Device Selection
Criteria" on page 5-5.
Gas Discharge Tubes
Gas tubes are either glass or ceramic packages filled with an inert gas and capped on each
end with an electrode. When a transient voltage exceeds the DC breakdown rating of the
device, the voltage differential causes the electrodes of the gas tube to fire, resulting in an
arc, which in turn ionizes the gas within the tube and provides a low impedance path for the

transient to follow. Once the transient drops below the DC holdover voltage and current, the
gas tube returns to its off state.
Advantages
Gas tubes have high surge current and low capacitance ratings. Current ratings can be as
high as 500 A for 200 impulses, and capacitance ratings can be as low as 1 pF with a zero-
volt bias.
Restrictions
Gas tubes have a limited shelf life and their performance degrades with usage. Out of the
four devices discussed, gas tubes exhibit the slowest response time and highest peak
voltage measurement. (Figure 5.3)
Applications
Because gas tubes are large and require a substantial amount of time to reach full
conduction, they are rarely used as board-level components. Consequently, gas tubes are
not normally used in telecommunications applications other than station protection
modules.
Metal Oxide Varistors
Metal Oxide Varistors (MOVs) are two-leaded, through-hole components typically shaped in
the form of discs. Manufactured from sintered oxides and schematically equivalent to two
back-to-back PN junctions, MOVs shunt transients by decreasing their resistance as
voltage is applied.
Advantages
Since MOVs surge capabilities are determined by their physical dimensions, high surge
current ratings are available. Also, because MOVs are clamping devices, they can be used
as transient protectors in secondary AC power line applications.
Restrictions
Like gas tubes, MOVs have slow response times resulting in peak clamping voltages which
can be greater than twice the device’s voltage rating. (Figure 5.3) MOVs also have long-
term reliability and performance issues due to their tendency to fatigue, high capacitance,
and limited packaging options.
Applications
Although MOVs are restricted from use in many telecom applications (other than disposable
equipment), they are useful in AC applications where a clamping device is required and
tight voltage tolerances are not.

Overvoltage Protection Comparison
TVS Diodes
Transient Voltage Suppressor (TVS) diodes are clamping voltage suppressors that are
constructed with back-to-back PN junctions. During conduction, TVS diodes create a low
impedance path by varying their resistance as voltage is applied across their terminals.
Once the voltage is removed, the diode will turn off and return to its high off-state
impedance.
Advantages
Because TVS diodes are solid state devices, they do not fatigue nor do their electrical
parameters change as long as they are operated within their specified limits. TVS diodes
effectively clamp fast-rising transients and are well suited for low-voltage applications that
do not require large amounts of energy to be shunted.
Restrictions
Because TVS diodes are clamping devices, they have two inherent weaknesses. First, TVS
diodes are both voltage- and current-limited, so careful consideration should be given to
using these in applications that require large amounts of energy to be shunted. Secondly,
as the amount of current flowing through the device increases, so does its maximum
clamping voltage.
Applications
Due to their low power ratings, TVS diodes are not used as primary interface protectors
across Tip and Ring; they are used as secondary protectors that are embedded within a
circuit.

Overcurrent Protection
Overcurrent Protection
In addition to protecting against overvoltage conditions, equipment should also be protected
from overcurrent conditions using either PTCs, fuses, power/line feed resistors, or
flameproof resistors. In all instances the overcurrent protector is a series element placed in
front of the overvoltage protector on either Tip or Ring for metallic (closed loop)
applications and on both Tip and Ring for longitudinal (grounded) applications.
PTCs
PTCs are positive temperature coefficient thermistors used to limit current. During a fault
condition, heat is generated at a rate equal to I2R. When this heat becomes sufficient, the
PTC increases its resistance asymptotically until the device simulates an open circuit,
limiting the current flow to the rest of the circuit. As the fault condition drops below the
PTC’s holding current, the device begins to reset, approximating its original off-state value
of impedance.
Advantages
Because PTCs are resettable devices, they work well in a variety of industrial applications
where electrical components cannot withstand multiple, low-current faults.
Restrictions
Although PTCs are well suited for the industrial environment and in many telecom
applications, they exhibit some limitations that have prevented them from being endorsed
by the entire telecommunications industry. Limitations include low surge current ratings,
unstable resistance, and poor packaging options.
Applications
PTCs are used in a variety of applications. In addition to protecting telecommunications
equipment, PTCs are also used to prevent damage to rechargeable battery packs, to
interrupt the current flow during a motor lock condition, and to limit the sneak currents that
may cause damage to a five-pin module.
Fuses
Due to their stability, fuses are one of the most popular solutions for meeting AC power
cross requirements for telecommunications equipment. Similar to PTCs, fuses function by
reacting to the heat generated due to excessive current flow. Once the fuses I2t rating is
exceeded, the center conductor opens.
Advantages
Fuses are available in both surface mount and through-hole packages and are able to
withstand the applicable regulatory requirements without the use of any additional series
impedance. Chosen correctly, fuses only interrupt a circuit when extreme fault conditions
exist and, when coordinated properly with an overvoltage protector, offer a very competitive
and effective solution for transient immunity needs.

Advantages include:

•
Elimination of series line resistance enabling longer loop lengths
Precise longitudinal balance allowing better transmission quality
Robust surge performance which eliminates costly down time due to nuisance blows
Greater surge ratings than resettable devices, ensuring regulatory compliance
Non-degenerative performance
Available in surface mount packaging which uses less Printed Circuit Board (PCB) real
estate, eliminates mixed technologies, and reduces manufacturing costs
Weaknesses
Because a fuse does not reset, consideration should be given to its use in applications
where multiple fault occurrences are likely. For example, AC strip protectors and ground
fault interrupting circuits (GFIC) are applications in which an alternative solution might be
more prudent.
Applications
Telecommunications equipment best suited for a fuse is equipment that requires surface
mount technology, accurate longitudinal balance, and regulatory compliance without the
use of additional series line impedance.
Selection Criteria
For circuits that do not require additional series resistance, the surge current rating (IPP) of
the TeleLink SM fuse should be greater than or equal to the surge currents associated with
the lightning immunity tests of the applicable regulatory requirement (IPK).
IPP OꢀIPK
For circuits that use additional series resistance, the surge current rating (IPP) of the
TeleLink SM fuse should be greater than or equal to the available surge currents associated
with the lightning immunity tests of the applicable regulatory requirement (IPK (available)).
IPP OꢀIPK (available)
The maximum available surge current is calculated by dividing the peak surge voltage (VPK
by the total circuit resistance (RTOTAL).

Power/Line Feed Resistors
Typically manufactured with a ceramic case or substrate, power and line feed resistors
have the ability to sink a great deal of energy and are capable of withstanding both lightning
and power cross conditions.
Advantages
Power and line feed resistors are available with very tight resistive tolerances, making them
appropriate for applications that require precise longitudinal balance.
Restrictions
Because power and line feed resistors are typically very large and are not available in a
surface mount configuration, these devices are less than desirable from a manufacturing
point of view. Also, because a thermal link is typically not provided, power and line feed
resistors may require either a fuse or a PTC to act as the fusing element during a power
cross condition.
Applications
Power and line feed resistors are typically found on line cards that use overvoltage
protectors that cannot withstand the surge currents associated with applicable regulatory
requirements.
Flameproof Resistors
For cost-sensitive designs, small (1/8 W - 1/4 W), flameproof metal film resistors are often
used in lieu of PTCs, fuses, and power or line feed resistors. During a transient condition,
flameproof resistors open when the resultant energy is great enough to melt the metal used
in the device.
Advantages
Flameproof resistors are inexpensive and plentiful.

Restrictions

PCB Layout
PCB Layout
Because the interface portion of a Printed Circuit Board (PCB) is subjected to high voltages
and surge currents, consideration should be given to the trace widths, trace separation, and
grounding.
Trace Widths
Based on the Institute for Interconnecting and Packaging Electronic Currents, IPC D 275
specifies the trace widths required for various current-carrying capacities. This is very
important for grounding conditions to ensure the integrity of the trace during a surge event.
The required width is dependent on the amount of copper used for the trace and the
acceptable temperature rise which can be tolerated. Teccor recommends a 0.025 inch trace
width with 1 ounce copper. (For example, a 38-AWG wire is approximately equal to 8 mils to
10 mils. Therefore, the minimum trace width should be greater than 10 mils.)

Conductor Cross-Section Area (sq mils)
Figure 5.4 Current versus Area
The minimum width and thickness of conductors on a PCB is determined primarily by the
current-carrying capacity required. This current-carrying capacity is limited by the allowable
temperature rise of the etched copper conductor. An adjacent ground or power layer can
significantly reduce this temperature rise. A single ground plane can generally raise the
allowed current by 50%. An easy approximation can be generated by starting with the
information in Figure 5.4 to calculate the conductor cross-sectional area required. Once this

Trace Separation
Tip and Ring traces are subjected to various transient and overvoltage conditions. To
prevent arcing between traces, minimum trace separation should be maintained. UL 60950
will provide additional information regarding creepage and clearance requirements, which
are dependent on the Comparative Tracking Index (CTI) rating of the PCB, working voltage,
and the expected operating environment. See "UL 60950 3rd Edition (formerly UL 1950, 3rd
edition)" on page 4-16 of this data book.
A good rule of thumb for outside layers is to maintain a minimum of 18 mils for 1kV isolation.
Route the Tip and Ring traces towards the edge of the PCB away from areas containing
static sensitive devices.
Grounding
Although often overlooked, grounding is a very important design consideration when laying
out a protection interface circuit. To optimize its effectiveness, several things should be
considered in sequence:
1. Provide a large copper plane with a grid pattern for the Ground reference point.
2. Decide if a single-point or a multi-point grounding scheme is to be used. A single-point
(also called centralized) grounding scheme is used for circuit dimensions smaller than
one-tenth of a wavelength (ꢄ = 300,000/frequency) and a multi-point (distributed)
grounding scheme is used for circuit trace lengths greater than one-fourth of a
wavelength.

PCB Layout
3. Because traces exhibit a certain level of inductance, keep the length of the ground trace
on the PCB as short as possible in order to minimize its voltage contribution during a
transient condition. In order to determine the actual voltage contributed to trace
inductance, use the following equations:
V = L (di/dt)
L = 0.0051 ꢅꢀ[loge 2 ꢅ/(t+w) +½ - logeG] in µH
where ꢅꢀ= length of trace
G = function of thickness and width as provided in Table 5.3
t = trace thickness
w = trace width
For example, assume circuit A is protected by a P3100SC with a VS equal to 300 V and a
ground trace one inch in length and a self-inductance equal to 2.4 µH/inch. Assume
circuit B has the identical characteristics as Circuit A, except the ground trace is five inches
in length instead of one inch in length. If both circuits are surged with a 100 A, 10x1000 µs
wave-form, the results would be as shown in Table 5.2:

Total protection level
VL = L (di/dt)
VL = 2.4 µH (100 A/10 µs) = 24 V

Other practices to ensure sound grounding techniques are:
1. Cross signal grounds and earth grounds perpendicularly in order to minimize the field
effects of “noisy” power supplies.
2. Make sure that the ground fingers on any edge connector extend farther out than any
power or signal leads in order to guarantee that the ground connection invariably is
connected first.

SIDACtor Soldering Recommendations
SIDACtor Soldering Recommendations
When placing surface mount components, a good solder bond is critical because:
•
The solder provides a thermal path in which heat is dissipated from the packaged silicon
to the rest of the board.
•
A good bond is less subject to thermal fatiguing and results in improved component
reliability.
Reflow Soldering
The preferred technique for mounting the DO-214AA package is to reflow-solder the device
onto a PCB-printed circuit board, as shown in Figure 5.6.
1. Screen print solder paste
(or flux)
2. Place component
(allow flux to dry)
3. Reflow solder
Figure 5.6 Reflow Soldering Procedure
For reliable connections, the PCB should first be screen printed with a solder paste or
fluxed with an easily removable, reliable solution, such as Alpha 5003 diluted with benzyl
alcohol. If using a flux, the PCB should be allowed to dry to touch at room temperature (or in
a 70 °C oven) prior to placing the components on the solder pads.
Relying on the adhesive nature of the solder paste or flux to prevent the devices from
moving prior to reflow, components should be placed with either a vacuum pencil or
automated pick and place machine.
With the components in place, the PCB should be heated to a point where the solder on the
pads begins to flow. This is typically done on a conveyor belt which first transports the PCB
through a pre-heating zone. The pre-heating zone is necessary in order to reduce thermal
shock and prevent damage to the devices being soldered, and should be limited to a
maximum temperature of 165 °C for 10 seconds.
After pre-heating, the PCB goes to a vapor zone, as shown in Figure 5.7. The vapor zone is
obtained by heating an inactive fluid to its boiling point while using a vapor lock to regulate
the chamber temperature. This temperature is typically 215 °C, but for temperatures in
excess of 215 °C, care should be taken so that the maximum temperature of the leads does

Figure 5.8 Reflow Soldering Profile
During reflow, the surface tension of the liquid solder draws the leads of the device towards
the center of the soldering area, correcting any misalignment that may have occurred
during placement and allowing the device to set flush on the pad. If the footprints of the pad
are not concentrically aligned, the same effect can result in undesirable shifts as well.
Therefore, it is important to use a standard contact pattern which leaves sufficient room for
self-positioning.
After the solder cools, connections should be visually inspected and remnants of the flux
removed using a vapor degreaser with an azeotrope solvent or equivalent.

Wave Soldering
Another common method for soldering components to a PCB is wave soldering. After
fluxing the PCB, an adhesive is applied to the respective footprints so that components can
be glued in place. Once the adhesive has cured, the board is pre-heated and then placed in
contact with a molten wave of solder which has a temperature between 240 °C and 260 °C
and permanently affixes the component to the PCB. (Figure 5.8 and Figure 5.10)
Although a popular method of soldering, wave soldering does have drawbacks:
•
•
•
A double pass is often required to remove excess solder.
Solder bridging and shadows begin to occur as board density increases.
Wave soldering uses the sharpest thermal gradient.

TeleLink Fuse Soldering
TeleLink Fuse Soldering
For wave soldering a TeleLink fuse, the following temperature and time are recommended:
•
•
Reservoir temperature of 260 °C (500 °F)
Time in reservoir — three seconds maximum
For infrared, the following temperature and time are recommended:
•
•
Temperature of 240 °C (464 °F)
Time — 30 seconds maximum
Hand soldering is not recommended for this fuse because excessive heat can affect the
fuse performance. Hand soldering should be used only for rework and low volume samples.
Note the following recommendations for hand soldering:
•
•
Maximum tip temperature of 240 °C (464 °F)
Minimize the soldering time at temperature to achieve the solder joint. Measure the fuse
resistance before and after soldering. Any fuse that shifts more than ±3% should be
replaced. An increase in resistance above this amount increases the possibility of a
surge failure, and a decrease in resistance may cause low overloads to exceed the
maximum opening times.
•
Inspect the solder joint to ensure an adequate solder fillet has been produced without
any cracks or visible defects.

Telecommunications Protection
Telecommunications Protection
Because early telecommunications equipment was constructed with components such as
mechanical relays, coils, and vacuum tubes, it was somewhat immune to lightning and
power cross conditions. But as cross bar and step-by-step switches have given way to more
modern equipment such as digital loop carriers, repeater amplifiers, and multiplexers, an
emphasis has been put on protecting this equipment against system transients caused by
lightning and power cross conditions.
Lightning
During an electrical storm, transient voltages are induced onto the telecommunications
system by lightning currents which enter the conductive shield of suspended cable or
through buried cables via ground currents.
As this occurs, the current traveling through the conductive shield of the cable produces an
equal voltage on both the Tip and Ring conductors at the terminating ends. Known as a
longitudinal voltage surge, the peak value and wave-form associated with this condition is
dependent upon the distance the transient travels down the cable and the materials with
which the cable is constructed.
Although lightning-induced surges are always longitudinal in nature, imbalances resulting
from terminating equipment and asymmetric operation of primary protectors can result in
metallic transients as well. A Tip-to-Ring surge is normally seen in terminating equipment
and is the primary reason most regulatory agencies require telecom equipment to have
both longitudinal and metallic surge protection.
Power Cross
Another system transient that is a common occurrence for telecommunications cables is
exposure to the AC power system. The common use of poles, trenches, and ground wires
results in varying levels of exposure which can be categorized as direct power cross, power
induction, and ground potential rise.
Direct power cross occurs when a power line makes direct contact to telecommunications
cables. Direct contact is commonly caused by falling trees, winter icing, severe
thunderstorms, and vehicle accidents. Direct power cross can result in large currents being
present on the line.
Power induction is common where power cables and telecommunications cables are run in
close proximity to one another. Electromagnetic coupling between the cables results in
system transients being induced onto the telecommunications cables, which in turn can
cause excessive heating and fires in terminal equipment located at the cable ends.
Ground potential rise is a result of large fault currents flowing to Ground. Due to the varying
soil resistivity and multiple grounding points, system potential differences may result.

Lightning
Lightning
Lightning is one of nature’s most common and dangerous phenomena. At any one time,
approximately 2,000 thunderstorms are in progress around the globe, with lightning striking
the earth over 100 times per second. According to IEEE C.62, during a single year in the
United States lightning strikes an average of 52 times per square mile, resulting in 100
deaths, 250 injuries, and over 100 million dollars in damage to equipment property.
The Lightning Phenomenon
Lightning is caused by the complex interaction of rain, ice, up drafts, and down drafts that
occur during a typical thunderstorm. The movement of rain droplets and ice within the cloud
results in a large build up of electrical charges at the top and bottom of the thunder cloud.
Normally, positive charges are concentrated at the top of the thunderhead while negative
charges accumulate near the bottom. Lightning itself does not occur until the potential
difference between two charges is great enough to overcome the insulating resistance of air
between them.
Formation of Lightning
Cloud-to-ground lightning begins forming as the level of negative charge contained in the
lower cloud levels begins to increase and attract the positive charge located at Ground.
When the formation of negative charge reaches its peak level, a surge of electrons called a
stepped leader begins to head towards the earth. Moving in 50-meter increments, the
stepped leader initiates the electrical path (channel) for the lightning strike. As the stepped
leader moves closer to the ground, the mutual attraction between positive and negative
charges results in a positive stream of electrons being pulled up from the ground to the
stepped leader. The positively charged stream is known as a streamer. When the streamer
and stepped leader make contact, it completes the electrical circuit between the cloud and
ground. At that instant, an explosive flow of electrons travels to ground at half the speed of
light and completes the formation of the lightning bolt.
Lightning Bolt
The initial flash of a lightning bolt results when the stepped leader and the streamer make
connection resulting in the conduction of current to Ground. Subsequent strokes (3-4) occur
as large amounts of negative charge move farther up the stepped leader. Known as return
strokes, these subsequent bolts heat the air to temperatures in excess of 50,000 °F and
cause the flickering flash that is associated with lightning. The total duration of most
lightning bolts lasts between 500 ms and one second.
During a lightning strike, the associated voltages range from 20,000 V to 1,000,000 V while
currents average around 35,000 A. However, maximum currents associated with lightning
have been measured as high as 300,000 A.
