Q145 / 200 · NEET 2022 (Phase 2) · Physics

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

  • A
    Zener voltage remains constant at breakdown
  • B
    It is designed to operate under reverse bias
  • Correct answer
    C
    Depletion region formed is very wide
  • D
    $\quad p$ and $n$ regions of zener diode are heavily doped

Solution

Zener diode is highly doped $p$ - $n$ junction, and zener voltage is constant. Its depletion region is very thin.

Hence, the correct answer is option: 'C'.
