Zener Diode

Zener Diode Voltage Regulator

Zener Diode is a general purpose diode, which behaves like a normal diode when forward biased. But when it is reverse biased above a certain voltage known as  zener breakdown voltage or zener voltage or avalanche point or zener knee voltage the voltage remains constant for a wide range of current. Clarence Zener is the scientist who discovered this electrical property and the device is named after him. Zener Diode Ordinary diodes will not have any significant current (only leakage current ) when reverse biased [...]
