| Zener Breakdown | Avalanche Breakdown |
|---|---|
| Both sides of PN junction are heavily doped in zener breakdown | Both sides of PN junction are lightly doped in avalanche breakdown |
| A strong electric field is produced | Electric field produced is weak |
| Large number of holes and electrons are produced | Electron hole pairs are generated |
| Zener current is independent of applied voltage | Charge carriers acquire energy from the applied potential |
