Semiconducting Devices Question 216
Question: Avalanche breakdown is due to
[RPMT 2001]
Options:
A) Collision of minority charge carrier
B) Increase in depletion layer thickness
C) Decrease in depletion layer thickness
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
At high reverse voltage, the minority charge carriers, acquires very high velocities.
These by collision break down the covalent bonds, generating more carriers.
This mechanism is called Avalanche breakdown.
