What is a Diode?

A diode is a device that only allows unidirectional flow of current if operated within a rated specified voltage level.

Working Principle of Diode

Its function is to let electric current flow in one direction but to prevent flow in the opposite direction.

Types of Diode

1. Zener diode 2. P-N junction diode 3. Tunnel diode 4. Varactor diode 5. Schottky diode 6. Photodiode 7. PIN diode 8. Laser diode 9. Avalanche diode 10. Light emitting diode
