BZW04-102BHB0G

BZW04-102BHB0G, also referred to as Transient Voltage Suppression (TVS) Diodes, is a two-terminal semiconductor device consisting of a Zener diode formed between the body and anode, and a TVS diode between the emitter and collector. In this article, we will explore the application field and the working principle of this device.

BZW04-102BHB0G is mainly used in the protection of transient voltage surges and electrostatic discharge (ESD) applications in the automotive, industrial, computing, and communication systems. This device is capable of handling high surge currents and prolonging the life of sensitive electronic components. It is also suitable for connecting to the terminal without the need for a separate diode bridge.

The working principle of BZW04-102BHB0G is based on two stages of protection. The first stage is an avalanche Zener diode. This diode provides protection to the device from transient voltage surges. When the input voltage exceeds its breakdown voltage, the Zener diode will enter the avalanche state, providing an extra current-carrying capability to reduce the noise. The second stage of protection is a TVS diode. This diode provides protection against electrostatic discharge (ESD) and other fast transients. It functions by clamping the voltage across the device when the input exceeds its breakdown voltage.

In summary, BZW04-102BHB0G belongs to the family of TVS Diodes, and it is mostly used in transient voltage surges and electrostatic discharge protection applications. Its working principle is based on the two stages of protection, an avalanche Zener diode and a TVS diode.
