Working Principle

A zener diode works by utilizing the breakdown voltage of a semiconductor. A zener diode allows current to pass in the forward direction until a predetermined voltage is reached, at which point the diode reverses the flow of current. This allows a precise voltage to be regulated. The CZRW5231B-G is a single zener diode and thus can only regulate a single voltage.

The breakdown voltage of the CZRW5231B-G is selected such that the precise desired voltage is regulated. When the current throughout the diode reaches the breakdown voltage of 5.1-5.3V, the diode reverses its flow and conducts in the reverse direction, creating a regulated voltage source. The current in the reverse direction depends on the external load resistance, resulting in precise regulation of the voltage.

Conclusion

The CZRW5231B-G is a single zener diode from Panjit designed for a wide range of applications such as voltage regulation, AC/DC conversion, overvoltage protection, noise suppression, and transient suppression. It has a zener voltage range of 5.1-5.3V, with a max current of 175mA, a max power rating of 500mW, and a forward voltage of 1.55V @ 25°C. The maximum operating temperature of 145°C makes it suitable for use in environments where high temperatures are encountered. The diode operates by utilizing the breakdown voltage of the semiconductor material, and can be finely tuned by adjusting the external load resistance.
