How does avalanche photodiode work?

An avalanche diode is a special type of semiconductor device designed to operate in the reverse breakdown mode. Avalanche diodes are used as over pressure valves (a type of valve…

How does photodiode detect light?

LEDs can also be used as photodiodes because they can emit and sense light from their junction. All PN junctions are photosensitive and can be used in a photoconductive, undistorted…

What is meant by avalanche photodiode?

An avalanche photodiode (APD) is a highly sensitive electronic semiconductor device that utilizes the photoelectric effect to convert light into electricity. High sensitivity and low noise, Fast reaction and Low-light…

What is Zener breakdown?

The Zener diode is a PN junction diode that was specially developed for operation in the blocking mode. In the forward bias mode, it acts as a normal diode. It has a…
