Question

what is zener diode and mention its applications​

Answer 1

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 Zener voltage is reached. ... Both breakdown types are used in Zener diodes with the Zener effect predominating at lower voltages and avalanche breakdown at higher voltages.

Applications of Zener diode

• Zener diodes are used in Voltage stabilizers (or) shunt regulators

used in Surge suppression circuitry for device protection

used in Over voltage protection circuits.

• Zener diodes are used in clipping and clamping circuits especially peak clippers .

• They are used as Reference elements.

• Used in switching applications.
