TVS (Transient Voltage Suppressor) diodes are electronic components designed primarily for over-voltage protection and electrical surge protection. The TVS diode serves as a protector by providing a high-speed, low-impedance shunt path for over-voltage/electrical surge protection. The ATV02W9V0B-HF TVS diode is one of the most popular devices in this category.

Application Field

The ATV02W9V0B-HF offers unparalleled protection in a wide range of applications. It can be used in consumer electronics, networking equipment, communication systems, automotive electronics, high voltage/high current supplies, and many more.

The ATV02W9V0B-HF has a surge capacity of 9V, so it is best suited for applications where the supply voltage can reach up to 9V. It is a bi-directional device, providing protection against both positive and negative transients. Additionally, its ultra-low clamping voltage makes it suitable for use with sensitive electronic components. With its high current dI/dt and low capacitance, this diode is suitable for use in high-speed applications.

Working Principle

The ATV02W9V0B-HF TVS diode utilizes a metal oxide varistor (MOV) to protect against over-voltage, over-current, and short circuit conditions. In the normal operating condition, the MOV acts like an insulator, blocking any current from flowing through it. However, when an over-voltage/current occurs, the MOV quickly becomes conductive, allowing the current to be shunted away from the protected circuit and the components to be saved from destruction.

The ATV02W9V0B-HF also features a reverse diode protection circuit which prevents a high voltage reverse current from damaging the MOV or other components in the circuit. This protection circuit allows the TVS diode to act as a thermal fuse in the event of an over-voltage or over-current surge.

Overall, the ATV02W9V0B-HF TVS diode is a powerful device for over-voltage/over-current protection applications. With its ultra-low clamping voltage, high surge capacity, low capacitance, and reverse diode protection circuit, the ATV02W9V0B-HF provides reliable and safe protection for a wide range of components and components.
