A Zener diode is a semiconductor diode device that has a special structure to allow it to act as a voltage regulator. This voltage regulator can be used to protect circuits and electronics from overcurrent, overvoltage or electrostatic discharge by clamping the voltage to a specific level when the predetermined limit is exceeded. The PLZ22A-G3/H Zener diode is a part of Fairchild’s line of Zener diodes. It provides 22V of fixed voltage at 3mA current. It has a Ultra-Fast recovery time and low dynamic interception point. This device features superior reliability and thermal performance, making it ideal for many applications.

Device Structure

The PLZ22A-G3/H is a single Zener diode, which means it consists of a single junction diode. This diode has an intrinsic layer that consists of an N-type and a P-type of silicon. The P-type side is heavily doped with a voltage regulating doping material and the N-type side is lightly doped. The PN junction is formed by combining these two sections, and the thickness of the intrinsic layer determines the breakdown voltage and other characteristics of the device.

Working Principle

The PLZ22A-G3/H is a single Zener diode device, so it works in a similar way to a regular diode, allowing electric current to flow only in one direction. However, due to its intrinsic layer and Zener voltage, it will regulate the voltage across the diode. If the voltage across it rises too high, current will start to flow through the diode and the voltage will be reduced to the regulated value. This regulated voltage can be used to protect other electronic components from overvoltage.

Application

The PLZ22A-G3/H is well suited for applications such as voltage clamps, voltage multipliers and overvoltage protection circuits. It is ideal for high-current and low-voltage applications and can be used in general purpose systems as a current-limiting device. It can also be used as an on/off switch in integrated circuits, allowing it to control the flow of current within the circuit. The device’s small size and low cost make it attractive for many applications where size and cost are important factors.

Conclusion

The PLZ22A-G3/H is a Zener diode device that provides 22V of fixed voltage at 3mA current and a very fast recovery time. It is well suited for many applications such as voltage clamps, voltage multipliers, overvoltage protection circuits and as an on/off switch in integrated circuits. It is ideal for high-current and low-voltage applications, and its small size and low cost make it attractive for many applications. It is a reliable and cost-effective way to provide voltage regulation and protection for electronic components.
