Question
A Zener diode:
✓
Answer
- Heavily doped junction diode.
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.
