MCQ
A Zener diode:
  • A
    Is a lightly doped junction diode.
  • B
    Heavily doped junction diode.
  • C
    Is either p-type or n-type.
  • D
    Has no p-n junction.

Answer

  1. Heavily doped junction diode.

Explanation:

The reverse breakdown voltage depends on doping of the diode. Hence, in the Zener diode the heavy doping of its p-n junction is done. The depletion region formed in the diode is very thin (<1 m) and the reverse bias voltage of about 5 V which is less than ordinary diode.
