Introduction to Zener Diode
A Zener diode is a special type of diode that operates in the reverse - breakdown region. Unlike ordinary diodes, which are designed to conduct current in the forward direction and block it in the reverse direction until a very high reverse voltage causes avalanche breakdown, Zener diodes are engineered to have a well - defined and stable reverse breakdown voltage, known as the Zener voltage (Vz).
When the reverse voltage across a Zener diode reaches its Zener voltage, the diode starts to conduct current in the reverse direction while maintaining a relatively constant voltage across its terminals. This characteristic makes Zener diodes extremely useful in voltage regulation circuits. They can be used to provide a stable reference voltage in power supplies, voltage clipping circuits to limit the voltage to a specific value, and in various other applications where a stable voltage is required.
