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: (d). (a) True: both p and n sides are heavily doped. (b) True: at breakdown the voltage stays constant at VZ. (c) True: it is designed to work in reverse bias. (d) False: heavy doping makes the depletion region very thin, not wide. So the answer is (d).

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

Show answer and solution

Answer: (d)

(a) True: both p and n sides are heavily doped.
(b) True: at breakdown the voltage stays constant at $V_Z$ .
(c) True: it is designed to work in reverse bias.
(d) False: heavy doping makes the depletion region very thin, not wide.
So the answer is (d).
