Zener Diode Working Principle

If the reverse bias voltage is less than the breakdown voltage, or if the Zener diode is forward biased, it acts as an ordinary diode. That is, in forward bias it allows current, and in reverse bias it blocks current.The Zener breakdown mainly occurs because of a high electric field. When the high electric-field is applied across the PN junction diode, then the electrons start flowing across the PN-junction. Consequently, expands the little current in the reverse bias.

A Zener diode is a type of diode that allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the voltage across its terminals exceeds the Zener voltage, a characteristic of the device.

The zener diode is a diode designed to operate in the breakdown region and have a specific negative voltage called the zener voltage. At this voltage, the diode will go into breakdown. This is a condition allowing current to flow while maintaining a constant voltage across the diode.
