Teaching MPPSC Assistant Professor Mock Test Series 2025 Electronic Devices PN Junction Types of Diode
Zener breakdown is different from avalanche breakdown in that
1
Zener breakdown occurs in weakly doped PN junction while avalanche breakdown occurs in highly doped junction
2
Zener breakdown occurs at reverse voltage smaller than avalanche breakdown
3
Junction is destroyed in Zener breakdown while avalanche breakdown reverse current flows without junction breakdown
4
In Zener breakdown lower electric fields exist in junction than avalanche breakdown
