The TV30C260JB-G TVS diode is an ideal solution for board level protection of analog and digital equipment from transient voltage spikes, and offers excellent transient protection for data, signal and power lines. It can be used in applications such as automotive, lightning protection, consumer electronics, mobile communications, and industrial electronics.

In automotive applications, the TV30C260JB-G provides protection against transients from the alternator, airbag inflation, ignition systems, ECUs, and fuel systems. In lightning protection applications, it is capable of handling multiple transient impacts, as well as withstand surges generated from nearby lightning strikes. In consumer electronics, the TV30C260JB-G is able to protect DVD players, HDTVs, digital set-top boxes, and other electronic devices from voltage spikes.

Working principle

The TV30C260JB-G is a bidirectional, SOT-26 packaged TVS diode with overvoltage protection from 30 to 260 volts. It is a Zener diode designed to ensure proper electronic equipment operation when subjected to transients caused by electrostatic discharge (ESD), lightning, or other high-voltage sources. The TV30C260JB-G can absorb high levels of ESD while preserving the signal integrity of protected lines. The Zener diode in this TVS has a breakdown voltage of 630V.

When the transient voltage exceeds this value, the Zener diode rapidly switches to its conduction mode, suppressing the transient voltage down to a safe level. The TV30C260JB-G also features soft clamping and fast response time (less than 1ns), capacitance of 7.0pF, and clamping voltage of 403V.

The TV30C260JB-G can handle high voltage transient events up to 400 volts, continuous reverse stand-off voltage up to 260 volts, and up to 800 watts (8/20 μs pulse) of maximum power dissipation. The TV30C260JB-G can also rectify the power line by blocking reverse currents. Its SOT-26 package provides a low-profile solution, allowing for easy mounting to a circuit board.

Conclusion

The TV30C260JB-G offers board level protection from transient voltage spikes, ESD, and other high-voltage sources. It is a bidirectional, SOT-26 packaged TVS diode with overvoltage protection from 30 to 260 volts. It is ideal for automotive, lightning protection, consumer electronics, mobile communications, and industrial electronics applications. The TV30C260JB-G provides fast response time (less than 1ns), soft clamping, and clamping voltage of 403V, making it an effective solution for protecting electronic components and equipment.
