Diodes - Zener - Single, What is their application field and how they work? In this article, we are going to answer these questions by taking BZT52C20S-TP as an example.

What is BZT52C20S-TP?

BZT52C20S-TP is a Zener diode, which is widely used in mounting devices with higher voltages. A Zener diode is a kind of semiconductor device which allows current to flow in both directions .That is to say, it works like a normal diode, but unlike normal diodes, it has a special feature - a "Zener effect". This effect generates a large reverse-bias voltage, causing the diode to act like a voltage reference source.

Characteristics of BZT52C20S-TP

BZT52C20S-TP is a 20V Zener Diode, with a maximum reverse voltage of 20V and maximum power dissipation of 0.7W. It also has a maximum reverse leakage current of 5mA, a typical forward voltage of 0.45V, and a junction capacitance of 6pF. The maximum junction temperature is 125℃.

Application Field of BZT52C20S-TP

BZT52C20S-TP is usually used in rectifier circuits, overvoltage protection circuits, and switching circuits as a voltage reference source. It can also be used in circuits that require a wide range of voltage stabilization and regulation.

Working Principle of BZT52C20S-TP

The working principle of BZT52C20S-TP can be understood by examining its electrical characteristics. When the diode is reverse-biased and the voltage across it is below the Zener voltage, no current will flow through it. However, when the reverse bias voltage exceeds the Zener voltage, a current will flow through it and the voltage across the diode will remain at the Zener voltage. In this way, the BZT52C20S-TP Zener diode acts as a voltage reference source.

Conclusion

In conclusion, BZT52C20S-TP is a Zener diode with a Zener voltage of 20V and a maximum power dissipation of 0.7W. It can be used in rectifier circuits, overvoltage protection circuits, and voltage regulator applications. Its working principle is that when the reverse bias voltage exceeds the Zener voltage, a current will flow through it and the voltage across the diode will remain at the Zener voltage.
