TISP4xxxM3LM Overvoltage Protector Series
TISP4xxxM3LM Overview
This TISP® device series protects central office, access and customer premise equipment against overvoltages on the telecom line. The
TISP4xxxM3LM is available in a wide range of voltages and has a medium current capability. These protectors have been specified mindful
of the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45.
The TISP4350M3LM meets the FCC Part 68 “B” ringer voltage requirement and survives the Type B impulse tests. These devices are housed
in a through-hole DO-92 package (TO-92 package with cropped center leg).

Description
These devices are designed to limit overvoltages on the telephone line. Overvoltages are normally caused by a.c. power system or lightning
flash disturbances which are induced or conducted on to the telephone line. A single device provides 2-point protection and is typically used
for the protection of 2-wire telecommunication equipment (e.g. between the Ring and Tip wires for telephones and modems). Combinations
of devices can be used for multi-point protection (e.g. 3-point protection between Ring, Tip and Ground).

TISP4xxxM3LM Overvoltage Protector Series
Description
The protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping
until the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. This low-voltage on state
causes the current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current prevents d.c.
latchup as the diverted current subsides.
This TISP4xxxM3LM range consists of seventeen voltage variants to meet various maximum system voltage levels (58 V to 320 V). They are
guaranteed to voltage limit and withstand the listed international lightning surges in both polarities. These protection devices are supplied
in a DO-92 (LM) cylindrical plastic package. The TISP4xxxM3LM is a straight lead DO-92 supplied in bulk pack and on tape and reel. The
TISP4xxxM3LMF is a formed lead DO-92 supplied only on tape and reel. For higher rated impulse currents in the DO-92 package, the 100 A
10/1000 TISP4xxxH3LM series is available.

FCC Part 68 terminology for the waveforms produced by the ITU-T recommendation K.21 10/700 impulse generator
If the impulse generator current exceeds the protector’s current rating, then a series resistance can be used to reduce the current to the
protector’s rated value to prevent possible failure. The required value of series resistance for a given waveform is given by the following
calculations. First, the minimum total circuit impedance is found by dividing the impulse generator’s peak voltage by the protector’s rated
current. The impulse generator’s fictive impedance (generator’s peak voltage divided by peak short circuit current) is then subtracted from the
minimum total circuit impedance to give the required value of series resistance.
For the FCC Part 68 10/560 waveform the following values result. The minimum total circuit impedance is 800/75 = 10.7 Ω and the gener-
ator’s fictive impedance is 800/100 = 8 Ω. This gives a minimum series resistance value of 10.7 - 8 = 2.7 Ω. After allowing for tolerance, a 3
Ω ±10ꢀ resistor would be suitable. The 10/160 waveform needs a standard resistor value of 5.6 Ω per conductor. These would be R1a and
R1b in Figure 15 and Figure 16. FCC Part 68 allows the equipment to be non-operational after the 10/160 (conductor to ground) and 10/560
(inter-conductor) impulses. The series resistor value may be reduced to zero to pass FCC Part 68 in a non-operational mode, e.g. Figure 14.
For this type of design, the series fuse must open before the TISP4xxxM3 fails. For Figure 14, the maximum fuse i2t is 2.3 A2s. In some cases,
the equipment will require verification over a temperature range. By using the rated waveform values from Figure 11, the appropriate series
resistor value can be calculated for ambient temperatures in the range of -40 °C to 85 °C.

TISP4xxxM3LM Overvoltage Protector Series
APPLICATIONS INFORMATION
AC Power Testing
The protector can withstand currents applied for times not exceeding those shown in Figure 8. Currents that exceed these times must be
terminated or reduced to avoid protector failure. Fuses, PTC (Positive Temperature Coefficient) resistors and fusible resistors are overcurrent
protection devices which can be used to reduce the current flow. Protective fuses may range from a few hundred milliamperes to one a
mpere. In some cases, it may be necessary to add some extra series resistance to prevent the fuse from opening during impulse testing. The
current versus time characteristic of the overcurrent protector must be below the line shown in Figure 8. In some cases there may be a further
time limit imposed by the test standard (e.g. UL 1459 wiring simulator failure).
Capacitance
The protector characteristic off-state capacitance values are given for d.c. bias voltage, V , values of 0, -1 V, -2 V and -50 V. Where possible,
D
values are also given for -100 V. Values for other voltages may be calculated by multiplying the V = 0 capacitance value by the factor given
D
in Figure 6. Up to 10 MHz, the capacitance is essentially independent of frequency. Above 10 MHz, the effective capacitance is strongly
dependent on connection inductance. In many applications, such as Figure 15 and Figure 17, the typical conductor bias voltages will be
about -2 V and -50 V. Figure 7 shows the differential (line unbalance) capacitance caused by biasing one protector at -2 V and the other at
-50 V.
Normal System Voltage Levels
The protector should not clip or limit the voltages that occur in normal system operation. For unusual conditions, such as ringing without the
line connected, some degree of clipping is permissible. Under this condition, about 10 V of clipping is normally possible without activating
the ring trip circuit.
Figure 10 allows the calculation of the protector V
maximum normal system voltages. The TISP4260M3LM, with a V
value at temperatures below 25 °C. The calculated value should not be less than the
DRM
of 200 V, can be used for the protection of ring generators producing
DRM
100 V rms of ring on a battery voltage of -58 V (Th2 and Th3 in Figure 17). The peak ring voltage will be 58 + 1.414*100 = 199.4 V. However,
this is the open circuit voltage and the connection of the line and its equipment will reduce the peak voltage. In the extreme case of an
unconnected line, clipping the peak voltage to 190 V should not activate the ring trip. This level of clipping would occur at the temperature
when the V
has reduced to 190/200 = 0.95 of its 25 °C value. Figure 10 shows that this condition will occur at an ambient temperature of
DRM
-28 °C. In this example, the TISP4260M3LM will allow normal equipment operation provided that the minimum expected ambient tempera-
ture does not fall below -28 °C.
JESD51 Thermal Measurement Method
To standardize thermal measurements, the EIA (Electronic Industries Alliance) has created the JESD51 standard. Part 2 of the standard
3
3
(JESD51-2, 1995) describes the test environment. This is a 0.0283 m (1 ft ) cube which contains the test PCB (Printed Circuit Board)
horizontally mounted at the center. Part 3 of the standard (JESD51-3, 1996) defines two test PCBs for surface mount components; one for
packages smaller than 27 mm (1.06 ’’) on a side and the other for packages up to 48 mm (1.89 ’’). The LM package measurements used the
smaller 76.2 mm x 114.3 mm (3.0 ’’ x 4.5 ’’) PCB. The JESD51-3 PCBs are designed to have low effective thermal conductivity (high thermal
resistance) and represent a worse case condition. The PCBs used in the majority of applications will achieve lower values of thermal resis-
tance and so can dissipate higher power levels than indicated by the JESD51 values.
