BZW04-6V4HA0G

Transient Voltage Suppressor Diodes (TVSs) are a special type of protection component used in various electronic systems to limit the effects of overvoltage. The BZW04-6V4HA0G is a popular unidirectional TVS diode utilized in many applications for continuous protection.

Applications

BZW04-6V4HA0G is designed to protect automotive electronic control systems against voltage spikes generated by induction or static discharge. This device can be found in contemporary cars, as well as other motor vehicles, helping protect against short-circuits, transients, and overloads. The unidirectional design means it will only conduct current when the voltage exceeds its breakdown voltage. Most applications use the BZW04-6V4HA0G for overvoltage protection near a voltage clamp, usually at the power supply input, or wherever there is a potential for overvoltage spikes. It can also be used in aircraft, telecommunications systems, medical equipment, and additional industrial grade electronic components.

Working Principle

The working principle of the BZW04-6V4HA0G relies on its PNP structure, which consists of two similar semiconductor resolutions connected between each other and a common term known as the cathode. When the voltage spike exceeds the breakdown voltage of the diode, the PNP transistor will turn on. This will cause current to flow through it, limiting the impact of the voltage spike on the protected component. The current capability of the BZW04-6V4HA0G is 200mA, with a maximum power dissipation of 800mW. This makes it suitable for high-voltage applications. Once the voltage spike is over, the PNP transistor will turn off, and the TVS diode will return to its original state.

Conclusion

The BZW04-6V4HA0G is a unidirectional Transient Voltage Suppressor Diode with a maximum breakdown voltage of 6V. This makes it suitable for a wide range of automotive, aircraft, and telecommunications applications. It works by allowing current to flow through the PNP transistor when the voltage spike exceeds its breakdown voltage, thus limiting the effect that the voltage spike has on the protected component. Many electronic systems rely on these types of TVS diodes to stay safe and functioning properly.
