Question: The incorrect statement about the property of a Zener diode is :#

A) $p$ and $n$ regions of Zener diode are heavily doped

B) Zener voltage remains constant at breakdown

C) It is designed to operate under reverse bias

D) Depletion region formed is very wide

Answer: Depletion region formed is very wide#

Sol:#

Zener diode is special purpose p-n junction diode, which is generally operated in reverse bias for its operation of voltage regulation. It is a heavily doped p-n junction. Due to large doping concentration depletion width is narrower.
