A Zener diode is a special kind of diode which allowsr current to flow in the forward direction in the same manner as an ideal diode,r but will also permit it to flow in the reverse direction when the voltage isr above a certain value known as the breakdown voltage, "Zener knee voltage"r or "Zener voltage." The device was named after Clarence Zener, whor discovered this electrical property.

A conventional solid-state diode will not allow significantr current if it is reverse-biased below its reverse breakdown voltage. When ther reverse bias breakdown voltage is exceeded, a conventional diode is subject tor high current due to avalanche breakdown. Unless this current is limited byr circuitry, the diode will be permanently damaged due to overheating. In ther case of a large forward bias (current in the direction of the arrow), the dioder exhibits a voltage drop due to its junction built-in voltage and internalr resistance. The amount of the voltage drop depends on the semiconductorr material and the doping concentrations.
