Zener diode - Basic Operation - Applications

What is a Zener diode?

The Zener diode is a special type of diode that allows the flow of current on the opposite direction of the arrow of the diode. This diode does not conduct until the applied voltage reaches or is greater of the breakdown voltage. Zener diode is very popular as Voltage reference element.
