Question

explain construction and working of avalanche photodiode?

Answer 1

Answer:

Construction And Working of Avalanche Diode. ... An avalanche diode is a one kind of diode that is designed to experience an avalanche breakdown at a particular reverse bias voltage. The junction of the diode is mainly designed to stop the concentration of current so that the diode is safe by the breakdown.

Answer 2

Generally, avalanche diode is made from silicon or other semiconductor materials. The construction of this diode is similar to the Zener diode, except doping level in this diode changes from Zener diode. These diodes are doped heavily. Thus, the depletion region width in this diode is very slight.
