Function of a Zener Diode

The function of a Zener diode is quite unique and this is a kind of diode that differs from most other regular diodes. Before you understand the complete function of a Zener diode, you need to take a look at the major functioning of a regular diode. In case of an ideal diode, the function is divided into two parts, forward and reverse bias. There is nothing much to talk about in forward bias as it is the reverse bias which is responsible for major discrepancies between ideal and Zener diode.
