What is zener diode

Question

What is zener diode

Accepted Answer

A zener diode is a type of diode that allows current to flow in the reverse direction when a certain voltage threshold is reached.

Zener diodes are commonly used in voltage regulation circuits.
They are designed to operate in the breakdown region, where a small change in voltage results in a large change in current.
Zener diodes are often used to protect sensitive electronic components from voltage spikes.
They can also be used in voltage reference circuits and as voltage limiters.
Zener diodes have a specific breakdown voltage, which determines the voltage at which they start conducting in the reverse direction.

Accepted Answer

The zener diode are normal p-n junction diodes it operating in a reverse biased condition

Zener diode can also conduct when it is connected in reverses biased above threshold/breakdown voltage
