effect of temperature on zener & avalanche breakdown

zener breakdown and avalanche breakdown.

Zener breakdown happens at low voltages, whereas avalanche breakdown happens at higher voltages. So diode with 6.2v is having zener breakdown rest is avalanche breakdown in this case.

Ther are generally Two types of Breakdown Phenomenons comes into picture. Namely-

1. Avalanche Breakdown

2. Zener Breakdown.

Silicon "zener diodes" with a zener voltage rating of 5.6V or higher operate mainly by avalanche breakdown, so both the 6.2V and 24V "zener diodes" are avalanche breakdown type (not zener breakdown type).
