CZRZ4V7B-HF - Diode - Zener - Single

The CZRZ4V7B-HF diode is a type of single zener diode that is specifically designed for use in commercial, industrial, and consumer circuits. It is especially suited for applications requiring high current-handling capability and robustness in situations where a general purpose diode is needed. The CZRZ4V7B-HF diode is able to handle large current surges and voltage spikes without malfunctioning, making it an excellent choice for protecting sensitive electronics.

Application Field

The CZRZ4V7B-HF diode is used in many different applications, such as power supply designs, DC/DC converters, line conditioning, and over-voltage protection. It is an ideal choice for regulating AC line voltage, since it can tolerate large voltage fluctuations. It is also widely used in automotive and industrial circuits, as it is reliable and has a long operating life.

Working Principle

The CZRZ4V7B-HF diode is a zener diode that operates on a principle known as avalanche breakdown. In this process, when a voltage greater than the rated zener voltage is applied, electrons are ejected from the material and create an electric field inside the diode. This electric field increases the current flow and produces a large noise called avalanche breakdown. This process is what allows the diode to regulate the voltage with great accuracy.

Properties and Features

The CZRZ4V7B-HF diode has a low forward voltage drop of only 0.5V and can handle up to 45V of reverse voltage. It has a maximum current rating of 10A and a maximum surge current of 20A.
