Advantages and disadvantages of avalanche photo diode

An avalanche photodiode is a one types of a diode. It is specially designed to work in the reverse breakdown region. In an avalanche photodiode is basically two terminal namely anode and cathode. It is basically PN junction diode which operates in the avalanche break down the region. This article gives information about the advantages and disadvantages of avalanche photodiode to know more details about it.

Advantages of avalanche photodiode :
  • Includes a greater level of sensitivity
  • High performance
  • Fast response time
Disadvantages of avalanche photodiode :
  • Much higher operating voltage required
  • The output is not linear
  • A much higher level of noise
  • Not as widely used due to low reliability
  • Requires high reverse bias for operation
