Zener diodes have major application for being used as a voltage regulator for providing stable reference voltages for use in power supplies, voltmeters, and other instruments. In this article, you will see how the Zener diode maintains (regulate) a nearly constant dc voltage under the proper operating conditions.

A PN junction is said to be forward biased when the externally applied voltage is in such a direction that it cancels the potential barrier of a diode, hence, allowing the current flow.
