In which of the following modes does a photodiode work?

Photodiode:

• A photodiode can convert light into either current or voltage depending upon the mode of operation.
• It is designed to operate in reverse bias.

Advantages of Photodiode:

• The photodiode is linear
• Low resistance
• A very good spectral response
• Better frequency response
• Low dark current
• Fastest photodetector
• It can be used as a variable resistance device
• Long lifetime, Low noise, High quantum efficiency, It is highly sensitive to the light
• Compact and lightweight
• No high voltage requires
• Using photodiode the speed of operation is very high
   

Disadvantages of Photodiode:

• Require increases in the dark current
• It depends on the temperature
• Small active area
• Normal PN junction photodiode has a very high response time
• It has very low sensitivity
• Light sensitive device
• Poor temperature stability
