A Zener diode

Question

Verified by Toppr

Answer 1

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.
