Working Principle

Zener Diode works in the reverse breakdown mode to regulate voltage. The Zener Diode has two semiconductor p and n type layers, separated by an insulating material called an intrinsic layer. With increased reverse bias current, the depletion region thickness increases, resulting in an increase of reverse breakdown voltage. The voltage at which reverse breakdown occurs is called the Zener Voltage. The BZD17C220PRTG diode is designed to maintain a precise voltage over a wide range of conditions. It has a reverse breakdown voltage of 220mV, a low Zener impedance at low pressures and can withstand high-voltage and high frequency. It also has high-temperature stability. At high temperatures, the BZD17C220PRTG can maintain a consistent voltage regulation despite changes in current and voltage.
