Question

zener diode definition

Answer 1

Zener diodes are a special kind of diode which permits current to flow in the forward direction. ... This breakdown voltage is known as the Zener voltage. In a standard diode, the Zener voltage is high, and the diode is permanently damaged if a reverse current above that value is allowed to pass through it.

Answer 2

$\underline \bold{Zener\: diode}$

​

Zener diode is a type of diode which is it different from other diode in one function. It can reverse the flow of current when Zener voltage is reached whereas in other diode it only flows from anode to its cathode.

Zener diode is connected in reverse bias.

It was invented by Clarence Melvin Zener and then after named after his name to Zener diode.

Zener diode is widely used as a shunt (parallel resistance) regulator to regulate the voltage in the circuit so as the voltage connot burn the circuit.

It is used in various ways such as voltage shifter, voltage regulator and waveform clipper.

In diode there is a change of voltage between forward bias and backward bias as shown in diagram

Forward bias means right side of x axis on graph.

Backward bias means left side of x axis on graph.
