Q. Avalanche breakdown in a p-n junction diode is due to

MGIMS WardhaMGIMS Wardha 2010

Solution:

At a particular value of reverse bias voltage, the covalent bonds near the junction break, so electron-hole pairs get liberated, this process rapidly multiplies and an avalanche of electron-hole pairs is produced, so choice is correct.
