what is diode

 what is diode?

·         Diode is semiconductor device

·         Diode is allow the flow of electric current only one direction

·         Diode have two terminals anode and cathode

·         Diode made with semiconductor material, ie. silicon, germanium.

Diode

Type of diode

·         Photo diode

·         Zener diode

·         Pin diode

·         Laser diode

·         Tunnel diode

·         P-n junction diode

·         Varactor diode

·         Light emitting diode(LED)

 Main function of diode 

             Diode is allow electric current in only one direction is called forward direction,

       Blocking electric current in the opposite direction is called reverse direction

  Use of diode 

·         a temperature sensor

·         a voltage controller

·         a simple voltage regulator

·         a signal switch

·         led

·         a rectifier( convert AC to pulsating DC)

·         a voltage limiter

·         a protect sensitive circuit
