Diodes and Applications

Diode Function: A semiconductor device that allows current to flow in one direction only, providing essential functionality in various electronic circuits.

Rectifier: Converts alternating current (AC) to direct current (DC), commonly used in power supplies.

Zener Diodes: Designed to allow current to flow in the reverse direction when a specific voltage is reached, often used for voltage regulation.

LEDs (Light Emitting Diodes): Emit light when current flows through them, widely used for indicators and displays.

Applications:

• Power conversion systems to stabilize output voltage.

• Signal demodulation in communication devices.

• Protection circuits to prevent back EMF in inductive loads. Rectification processes in power supplies convert AC to DC.
