In this blog we will be discussing about different types of diode and symbol. A diode is basically two terminal electronic device which allows current to flow in one direction while it blocks the current in other direction.

It is made of two types of semiconductor materials namely p-type and n-type. By varying the properties of these materials different types of of diode are manufactured. Here are some different type of diodes described as follow.

  1. Schottky diode
  2. PN junction diode
  3. Avalanche diode
  4. Zener diode
  5. Light Emitting Diode
  6. Photodiode
  7. Laser diode

Step Recovery Diode Symbol, Construction, Working & Applications

A Step Recovery Diode (SRD) is a special type of semiconductor diode also called as snap-off diode, charge storage diode and memory varactor diode. Step recovery diodes are having a different style of doping. It is not like a normal PN junction diode, it is a voltage dependent variable capacitor. The density of charge carrier […]

Gunn Diode Working Principle VI Characteristics & Applications

Gunn diode operates on the Gunn effect which is named after its inventor J.B. Gunn. He discovered the periodic variation of current in a GaAs (gallium arsenide) rod in 1963. The microwave device that operates on the principle of transfer of electrons is called as Gunn diode. This is one of the diodes used as […]

Shockley Diode Symbol Construction, Working and Applications

You can see Shockley diode symbol it is a four-layer (P-N-P-N) semiconductor device. Like pn junction diode It conducts in forward bias and stops conducting in reverse bias. The main difference between a conventional diode and a Shockley diode is, it starts conducting when the forward voltage crosses its breakdown voltage. It is an active component. It […]

Definition of Diode, VI Characteristics, Working and Application

The definition of diode is very simple, “A diode is a two-terminal polarized electronic component which mainly conducts current in one direction and blocks in other direction”. Its resistance in one direction is low (ideally zero) and high (ideally infinite) resistance in the other direction. There are various types of Diodes like Zener, Schottky, tunnel, […]
