Part A What is a Zener diode? What is a Zener diode? A Zener diode is a diode intended for operation in the forward-bias region. A Zener diode is a diode intended for operation in the forward breakdown region. A Zener diode is a diode intended for operation in the reverse breakdown region. A Zener diode is a diode intended for operation in the reverse-bias region.

All options are correct

Explanation:

A Zener diode is a silicon semiconductor devise that permits current to flow in either a forward or reverse direction. The diode consists of special heavy dop p-n junction, designed to conduct in reverse direction when a certain specified voltage is reached.

A zener diode operates in both forward and reverse bias regions. A zener diode has well defined reverse breakdown voltage.
