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

Options

  1. AZener voltage remains constant at breakdown
  2. BIt is designed to operate under reverse bias
  3. CDepletion region formed is very wide
  4. Dp and n regions of zener diode are heavily doped

Correct answer

C. Depletion region formed is very wide

Step-by-step solution

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