Zener Diode:

Zener diodes are normal PN junction diodes operating in reverse-biased conditions.
The working of the Zener diode is similar to a PN junction diode in forward biased condition, but the uniqueness lies in the fact that it can also conduct when it is connected in reverse bias above its threshold/breakdown voltage.
It is operated in a breakdown region.
A Zener diode is used as a voltage regulator in reverse biased mode.
The breakdown voltage in the Zener diode when connected in the reverse-biased is called Zener voltage.
This Zener voltage so steady and constant, it has huge applications in circuits, most importantly, voltage regulation.
From the above explanation, we can see that the Zener diode is fabricated by heavily doped p-side and lightly doped n-side, which help it in operating in reverse bias.
