Introduction

TVS - Diodes, also known as Transient Voltage Suppressors, are components often used in an electronic system to protect against voltage spikes. In this article, we will discuss the application field and working principle of the BZW04-10HR1G.

Applications

The BZW04-10HR1G is a DO-15 package unidirectional Transient Voltage Suppressor (TVS) designed for circuit protection. It is mainly used in various equipment in the automotive industry, such as in electric vehicle charging systems, electric power steering systems, parking systems, and interior lighting systems. It is also widely used in home appliances, such as printers, televisions, air conditioners, refrigerators, and washing machines. It is suitable for low capacitance requirements, low clamping voltage, high peak pulse power, and low surge.

Working Principle

The BZW04-10HR1G is a unidirectional TVS diode, meaning it only conducts current in one direction. When the voltage at the TVS diode surpasses the breakdown voltage (V＜BR+), the reverse breakdown will occur and the voltage will experience a sharp decrease. When the reverse polarized voltage is lower than BR, the current will automatically stop flowing. Therefore, when there is a voltage spike, the BZW04-10HR1G will clamp the voltage to prevent the circuit from being damaged, thus providing a safe and reliable operation.

Conclusion

To summarize, the BZW04-10HR1G is a DO-15 package unidirectional TVS designed for circuit protection. Its main application is in the automotive and home appliance industries, and it is suitable for low capacitance requirements, low clamping voltage, high peak pulse power, and low surge. Its working principle is that when the reverse polarized voltage is higher than BR+, the current will automatically flow and the voltage will decrease, and when it is lower than BR, the current will automatically stop flowing.
