On increasing the reverse bias to a large value in a PN-junction diode, current.
As we learnt in
Zener diode -
It can operate continuously without being damaged in the region of reverse biased
1) It acts as voltage regulator
2) In forward biasing it act as ordinary diode .
On increasing reverse bias to a large value in a PN junction diode,current suddenly increase due to Zener / Avalanche breakdown.
