8 Detailed Description
8.1 Overview
The TVS2701 is a bidirectional precision clamp with two integrated FETs driven by a feedback loop to tightly
regulate the input voltage during an overvoltage event. This feedback loop leads to a very low dynamic
resistance, giving a flat clamping voltage during transient overvoltage events like a surge.
8.2 Functional Block Diagram
8.3 Feature Description
The TVS2701 is a precision clamp that handles 27 A of IEC 61000-4-5 8/20-µs surge pulse. The flat clamping
feature helps keep the clamping voltage very low to keep the downstream circuits from being stressed. The flat
clamping feature can also help end-equipment designers save cost by opening up the possibility to use lower-
cost, lower voltage tolerant downstream ICs. This device provides a bidirectional operating range, with a
symmetrical VRWM of ±27 V designed for applications that have bipolar input signals or that must withstand
reverse wiring conditions. The TVS2701 has minimal leakage at VRWM, designed for applications where low
leakage and power dissipation is a necessity. Built-in IEC 61000-4-2 and IEC 61000-4-4 ratings make it a robust
protection solution for ESD and EFT events and the TVS2701 wide ambient temperature range of –40°C to
+125°C enables usage in harsh industrial environments.
8.4 Device Functional Modes
8.4.1 Protection Specifications
The TVS2701 is specified according to both the IEC 61000-4-5 and IEC 61643-321 standards. This enables
usage in systems regardless of which standard is required by relevant product standards or best matches
measured fault conditions. The IEC 61000-4-5 standard requires protection against a pulse with a rise time of 8
µs and a half-length of 20 µs, while the IEC 61643-321 standard requires protection against a much longer pulse
with a rise time of 10 µs and a half-length of 1000 µs.

ZHCSIV6A –SEPTEMBER 2018–REVISED DECEMBER 2018
Device Functional Modes (接下页)
The positive and negative surges are imposed to the TVS2701 by a combination wave generator (CWG) with a
2-Ω coupling resistor at different peak voltage levels. For powered-on transient tests that need power supply
bias, inductances are used to decouple the transient stress and protect the power supply. The TVS2701 is post-
tested by assuring that there is no shift in device breakdown or leakage at VRWM
.
In addition, the TVS2701 has been tested according to IEC 61000-4-5 to pass a ±1-kV surge test through a 42-Ω
coupling resistor and a 0.5-µF capacitor. This test is a common test requirement for industrial signal I/O lines and
the TVS2701 precision clamp can be used in applications that have that requirement.
The TVS2701 integrates IEC 61000-4-2 level 4 ESD Protection and 80 A of IEC 61000-4-4 EFT Protection.
These combine to ensure that the device can protect against most common transient test requirements.
For more information on TI's test methods for Surge, ESD, and EFT testing, refer to the IEC 61000-4-x Tests for
TI's Protection Devices application report.
8.4.2 Reliability Testing
To ensure device reliability, the TVS2701 is characterized against 5000 repetitive pulses of 25-A IEC 61000-4-5
8/20-µs surge pulses at 125°C. The test is performed with less than 10 seconds between each pulse at high
temperature to simulate worst-case scenarios for fault regulation. After each surge pulse, the TVS2701 clamping
voltage, breakdown voltage, and leakage are recorded to ensure that there is no variation or performance
degradation. By ensuring robust, reliable, high temperature protection, the TVS2701 enables fault protection in
applications that must withstand years of continuous operation with no performance change.
8.4.3 Zero Derating
Unlike traditional diodes, the TVS2701 has zero derating of maximum power dissipation and ensures robust
performance up to 125°C. Traditional TVS diodes lose up to 50% of their current carrying capability when at high
temperatures, so a surge pulse above 85°C ambient can cause failures that are not seen at room temperature.
The TVS2701 prevents this so the designer can see the surge protection regardless of temperature. Because of
this, Flat-Clamp devices can provide robust protection against surge pulses that occur at high ambient
temperatures, as shown in TI's TVS Surge Protection in High-Temperature Environments application report.
8.4.4 Bidirectional Operation
The TVS2701 is a bidirectional TVS with a symmetrical operating region. This allows for operation with positive
and negative voltages, rather than just positive voltages like the unidirectional TVS2700. This allows for single
chip protection for applications where the signal is expected to operate below 0 V or where there is a need to
withstand a large common-mode voltage. In addition, in many cases, there is a system requirement to be able to
withstand reverse wiring conditions, in many cases where a high voltage signal is accidentally applied to the
system ground and a ground is accidentally applied to the input terminal. This causes a large reverse voltage on
the TVS diode that the device must be able to withstand. The TVS2701 is designed to not break down or see
failures under reverse wiring conditions, for applications that must withstand these miswiring issues.
注
If the applied signal is not expected to go below 0 V, a unidirectional device will clamp
much lower in the reverse direction and should be used. In this case, the recommended
device would be the TVS2700.
8.4.5 Transient Performance
During large transient swings, the TVS2701 will begin clamping the input signal to protect downstream
conditions. While this prevents damage during fault conditions, it can cause leakage when the intended input
signal has a fast slew rate. To keep power dissipation low and remove the chance of signal distortion, TI
recommends that the designer keep the slew rate of any input signal on the TVS2701 below 2.5 V/µs at room
temperature and below 1.0 V/µs at 85°C shown in 图 6. Faster slew rates will cause the device to clamp the
input signal and draw current through the device for a few microseconds, increasing the rise time of the signal.
This will not cause any harm to the system or to the device, however if can cause device overheating if the fast
input voltage swings occur regularly.

9 Application and Implementation
注
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The TVS2701 can be used to protect any power, analog, or digital signal from transient fault conditions caused
by the environment or other electrical components. A common application will be protecting both the PLC and
sensor transmitter in industrial applications, as shown. More detail will be given on the protection on the PLC
side as the input signal is connected to the input of a multiplexer.

ZHCSIV6A –SEPTEMBER 2018–REVISED DECEMBER 2018
Typical Application (接下页)
9.2.1 Design Requirements
A typical operation for the TVS2701 would be in a multi-channel PLC protecting an analog input, shown in 图 8.
In this example, a TVS2701 is protecting the input to a MUX36D04, a four channel input multiplexer with a supply
maximum at 36 V. In addition, the application must be able to withstand reverse wiring conditions with no
damage caused to the input circuitry. Without any input protection, this input voltage will rise to hundreds of volts
for multiple microseconds and violate the absolute maximum input voltage and harm the device if a surge event
is caused by lightning, coupling, ringing, or any other fault condition. TI'd Flat-Clamp technology provides surge
protection diodes that can maximize the useable voltage range and clamp at a safe level for the system.
9.2.2 Detailed Design Procedure
If the TVS2701 is in place to protect the device, the voltage will rise to the breakdown of the diode at 32 V during
a surge event. The TVS2701 will then turn on to shunt the surge current to ground. With the low dynamic
resistance of the TVS2701, even large amounts of surge current will have minimal impact on the clamping
voltage. The dynamic resistance of the TVS2701 is around 40 mΩ, which means a 25-A surge current will cause
a voltage raise of 25 A × 40 mΩ = 1 V. Because the device turns on at 32 V, this means the module input will be
exposed to a maximum of 32 V + 1 V = 33 V during surge pulses, well within the MUX36D04 absolute maximum.
In addition, because the TVS2701 is a bidirectional device it is designed to withstand reverse wiring conditions.
When the supplies is wired backwards, it applies –27 V to the VINPUT relative to ground, which does not break
down the TVS diode, and does not damage the input to the MUX36D04 because of the reverse current
protection diode. If a unidirectional diode like the TVS2700 were used in this case, the –27 V would cause the
diode to shunt current until it overheat and breaks.
Finally, the small size of the device also improves fault protection by lowering the effect of fault current coupling
onto neighboring traces. The small form factor of the TVS2701 allows the device to be placed extremely close to
the input connector, which lowers the length of the path fault current going through the system compared to
larger protection solutions.
9.2.3 Application Curves
When a surge is applied to the system with the TVS2701, the device will clamp the surge as shown in 图 9.

11 Layout
11.1 Layout Guidelines
The optimum placement is close to the connector. EMI during an ESD event can couple from the tested trace to
other nearby unprotected traces, which could result in system failures. The PCB designer must minimize the
possibility of EMI coupling by keeping all unprotected traces away from protected traces between the TVS and
the connector. Route the protected traces straight. Use rounded corners with the largest radii possible to
eliminate any sharp corners on the protected traces between the TVS2701 and the connector. Electric fields tend
to build up on corners, which could increase EMI coupling.
Ensure that the thermal pad on the layout is floating rather than grounded. Grounding the thermal pad will
impede the operating range of the TVS2701, and can cause failures when the applied voltage is negative. A
floating thermal pad allows the maximum operating range without sacrificing any transient performance.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
