Choose the correct statement about Zener diode: (a) It works as a voltage regulator in reverse bias and behaves like simple pn junction diode in forward bias. (b) It works as a voltage regulator in both forward and reverse bias. (c) It works as a voltage regulator only in forward bias. (d) It works as a voltage regulator in forward bias and behaves like simple pn junction diode in reverse bias.

Answer: (a). In reverse bias, at breakdown the voltage stays fixed at VZ, so it regulates voltage. In forward bias it conducts like a normal p-n junction diode. So the answer is (a).

Choose the correct statement about Zener diode:

Show answer and solution

Answer: (a)

In reverse bias, at breakdown the voltage stays fixed at $V_Z$ , so it regulates voltage.
In forward bias it conducts like a normal p-n junction diode.
So the answer is (a).
