Transient Voltage Suppressors (TVS) are widely used for their versatility and functionality in a range of applications. Their transient voltage protection and electronic protection capabilities make them suitable for ESD elimination, surge protection, leakage protection and high-voltage clamping. The ATV02W400B-HF is one of these devices, and its application field and working principle are explored in this paper.

Application Field

The ATV02W400B-HF TVS Diode is designed to protect sensitive electronics from transient voltages and other transient threats. It is suitable for both commercial applications for Industrial data networks, and automotive applications such as EMI protection in electrical/electronic systems. It features a low leakage current rating, a low capacitance rating and a low clamping voltage allowing it to protect sensitive components from various transient risks without interfering with the normal operation of the system.

Working Principle

The ATV02W400B-HF uses a rapid-response avalanche breakdown mechanism that causes voltage and current peaks to fall below their threshold, providing effective protection from transient events. The main components of the ATV02W400B-HF are a semiconductor p-n junction, an avalanche region and a breakdown resistor. When a transient voltage is applied to the p-n junction, the current at the junction increases before reaching a steady state, causing the junction to enter the avalanche region. In this region, the voltage drops and the current vastly increases, until it reaches the breakdown resistor. At this point, the current is diverted to the ground, eliminating the transient event from the system.

Conclusion

The ATV02W400B-HF device is a powerful tool for providing efficient and effective protection against transient events in electrical and electronic systems. Its low leakage current and capacitance as well as its low clamping voltage allow it to protect sensitive components from transient events without interfering with the normal operation of the system. With its rapid-response avalanche breakdown mechanism, it provides effective protection from transient voltages and other transient risks. As such, it is suitable for a range of applications, both commercial and automotive.
