The doping level in a zener diode is______________ that of a crystal diode?
Correct answer: C. more than
- A. the same as
- B. less than
- C. more than
- D. none of the above
Explanation
A zener diode is heavily doped compared with an ordinary crystal diode, producing a thin depletion region and a controlled breakdown voltage. Hence its doping level is more than that of a crystal diode.
