Diodes are an essential electrical component used in virtually all types of circuits. They are commonly employed to allow current to pass in one direction while blocking its flow in the opposite direction. Zener diodes are a special type of diode that are designed to conduct in one direction and also break down under a certain reverse voltage. This breakdown is a highly stable effect and can be used to create precision voltage references and limiting. Single zener diodes are further classified based on their peak inverse voltage (PIV) rating and power dissipation rating. One of the most commonly used type of single zener diode is the PLZ30A-HG3/H. This device has a PIV rating of 30V and a power dissipation rating of 500mW.

The PLZ30A-HG3/H is primarily used for voltage regulation and/or voltage limiting. It can be used in a wide range of applications, such as power supplies, automotive electronics, distributed networks, and digital communication systems. It is also used as a protection diode in high-precision piezo-electric actuators.

The working principle behind the PLZ30A-HG3/H is based on the breakdown voltage of a zener diode. When the reverse voltage across the device is below a certain threshold, the current flows mainly in the forward direction. When the reverse voltage exceeds this threshold, it triggers an avalanche breakdown effect that allows current to flow in the opposite direction. This breakdown voltage is highly repeatable and stable, allowing it to be used to create precision voltage references and limits.

The breakdown voltage of the PLZ30A-HG3/H is 30V and its maximum reverse leakage current is 1mA. The maximum power dissipation is 500mW, which makes it suitable for a wide range of applications. Additionally, it has a low forward voltage drop, low reverse recovery time, and high temperature coefficient.

In summary, the PLZ30A-HG3/H is a single zener diode, with a PIV rating of 30V and power dissipation rating of 500mW. It is mainly used for voltage regulation and/or voltage limiting in a variety of applications. The device takes advantage of the breakdown voltage of the diode in order to provide a highly stable output voltage. It also features a low forward voltage drop, low reverse recovery time, and high temperature coefficient.
