Assignment Help:

Can an ordinary diode be used as a zener diode? Justify your answer.

Ans

Ordinary diode can't be used as a Zener diode, since ordinary diodes aren't operated  in  the  reverse  bias  breakdown  region  to  avoid  them  from  damaging.  These diodes  are  generally operated  in  forward  region  and  never  operated  in  reverse  region, as small  signal  and  rectifier  diode  are  never  operated  in  breakdown  (or  reverse region). Zener diode is a specially designed silicon diode that is optimized to operate in the breakdown region.
