Diode

A diode is a semiconductor component that allows Current to flow in only one direction, blocking reverse Current.

Definition

Diodes are used for rectification (converting AC to DC), protection (preventing reverse Voltage), and signal routing. An LED is a special type of diode that emits light.

Key Points

  • Allows Current in one direction only
  • Has a forward Voltage drop (typically 0.7V for silicon)
  • Used for rectification and protection
  • LEDs are light-emitting diodes
  • Essential for power supplies and signal routing
