Introduction

The ZPY22-TR is an innovative two-terminal Zener diode with a voltage rating up to 22V. It is a heavily doped PN junction diode with a low Zener voltage and current rating. This diode has a maximum electric field of 40V/μm, a low forward voltage drop of 0.6V, and a reverse breakdown voltage of 22V. A wide range of applications can be served with the use of the ZPY22-TR, including voltage regulation, voltage reference, ESD protection, overvoltage protection and low voltage clamps.

Application Field

The ZPY22-TR has a wide range of applications because of its reliable performance and low voltage regulation characteristics. It can be used as a voltage regulator in electronic systems to automatically control the maximum or minimum voltage levels. It can also be used as a voltage reference in low-voltage power supplies, providing a stable voltage reference for further circuits, often for power supply design or lower noise. The ZPY22-TR can also be used as an ESD protector due to its high impedance at low voltages and high current capacity at high voltages, making it suitable for protecting components from incoming intensive transients. It can also be used as an overvoltage protection device in power supply design, providing an easy to implement overvoltage protection solution. It can also be used as a low voltage clamp in systems that require a low voltage clamp.

Working Principle

The ZPY22-TR is a two-terminal Zener diode, meaning it is composed of two oppositely-charged layers (a P-type layer and an N-type layer). The N-type layer is heavily doped with impurities, making it highly conductive and creating a low-resistance Path. When the voltage at the two terminals falls below the breakdown voltage, the diode is said to enter a Zener breakdown state in which current can easily flow through the diode. When the voltage is above the breakdown voltage, the diode is in the high impedance state and no current flows through the diode. The ZPY22-TR has a low Zener voltage and current rating, which enables its application in voltage regulation, voltage reference and overvoltage protection.

Conclusion

The ZPY22-TR is an innovative two-terminal Zener diode with a voltage rating up to 22V. It is heavily doped PN junction diode with a low Zener voltage and current rating, making it suitable for different applications including voltage regulation, voltage reference, ESD protection, overvoltage protection and low voltage clamps. The working principle of the ZPY22-TR is based on the low Zener voltage and current rating, which enables its application for voltage regulation and reference applications.
