Answer Posted / prakash
Zener breakdown and Avalanche breakdown both are under
reverse bias.which are responsible for such large reverse
current.
Avalanche:-It takes place due to the drift of thermally
generated minority carriers through the junction under the
influence of external field.
Zener breakdown:-It takes place due to presence of strong
electric field and presence of large reverse bias voltage
