CZRSC55C2V2-G application field and working principle

The CZRSC55C2V2-G is a small signal Zener diode designed for a wide variety of applications. It is a single-discrete-component assembly. The device has a breakdown voltage of 2.2V and a maximum DC operating power of 500mW.

The Application Field of CZRSC55C2V2-G:

The CZRSC55C2V2-G Zener diode is most suitable for applications such as protection circuits, digital logic control, or rectification circuits. It can be used for applications like switching regulators and inductors for use as components for high voltage power supplies. It also finds application in power converters, and light dimmers. This diode can be used to provide over-voltage and over-current protection in linear voltage regulators.

The Working Principle of CZRSC55C2V2-G:

The CZRSC55C2V2-G is a Zener diode, and it functions by utilizing the Zener voltage. When a diode is forward biased, it acts as a closed switch. In this mode, current flows through the diode and hole pairing happens in the junction. The total current in this mode is the sum of the electron and hole current. When the junction of the diode is reverse biased, current does not flow through it. However, when the reverse bias voltage is above the Zener voltage, some electrons from the n-type region tunnels into the depleted p-type region, and current is conducted. This current is limited by the bias voltage; for example, if the reverse bias is 10V, then the conduction current through the junction is limited to 10V/2.2KΩ, which is around 4.5mA. Thus, the Zener diode regulates the output or stabilizes the voltage.

Conclusion:

The CZRSC55C2V2-G Zener diode finds its application in various fields such as protection circuits, rectification circuits, and applications requiring high voltage switching. The main working principle of the diode is to use the Zener voltage to regulate the output or stabilize the voltage.
