06-07-21 DIODE

Diode:- Diode limits the current, It means that it allows electric current to go only in one direction.

It is a polarised component with two leads, called the Anode(+) & the Cathode(-). The cathode is normally marked with a Silver or colour band.

Potential Barrier:- 

1) 0.7 volts for Silicon

2) 0.3 volts for Germanium

Types of Diode:- 

1) Zener diode

2) P-N junction diode

3) Tunnel diode

4) Photo diode

5) Laser diode

6) LED 

7) PIN diode.

Uses of Diode:- Diode can be used as Rectifiers, Signal limiters, Voltage Regulators, Switches, Signal Modulators, Oscillators.

The fundamental property of a diode is its tendancy to conduct electric current in only one direction.
