Question

What are the different types of functions and operations of diode?

Answer 1

Basically, a diode allows the flow of current in only one direction. The different types of diodes are as follows. Please see links below for more details:

Avalanche diodes

Cat’s whisker or crystal diodes

Constant current diodes

Esaki or tunnel diodes

Gunn diodes

Light-emitting diodes (LEDs)

Laser diodes

Peltier diodes

Photodiodes

Point-contact diodes

PIN diodes

Schottky diodes

Super Barrier Diodes

Gold-doped” diodes

Snap-off or Step recovery diodes

Transient voltage suppression diode (TVS)

Varicap or varactor diodes

Zener diodes

Some applications for diodes are as follows:

Radio demodulation

Power conversion

Over-voltage protection

Logic gates

Ionising radiation detectors

Temperature measuring

Current steering

Answer 2

The diode allows current to pass through one direction. It is always used to convert A.C to D.C(rectifying). It also allows current only when a specific amount of voltage is applied(0.3,0.7). So it can be used as a switch also.

The operations of diodes are already stated by the above guy!!!!!!!!!
