Zener diode is a diode which is used in its break down region. The diode is kept reverse biased in a circuit, and so it does not allow current to pass until the voltage is greater than the breakdown voltage of the zener.
Diode - Semiconductor diodes. 1  The symbol used for a semiconductor diode in a circuit diagram specifies the type of diode. 2  Light-emitting diode (LED) 3  Photodiode. 4  Schottky diode. 5  Transient-voltage-suppression diode (TVS) 6  Tunnel diode. 7  Zener diode. 8  Typical diode packages in same alignment as diode symbol.
