  1. Diode

  2. Introduction A diode is an electrical device allowing current to move through it in one direction with far greater ease than in the other.

  3. FABRICATION

  4. CHARACTERISTICS

  5. OPERATION • When placed in a simple battery-lamp circuit, the diode will either allow or prevent current through the lamp, depending on the polarity of the applied voltage. • Diode operation: (a) Current flow is permitted; the diode is forward biased. (b) Current flow is prohibited; the diode is reversed biased

  6. TYPES OF DIODES

  7. Applications of diodes • Signal rectifier • Diode gate • Diode clamps • Limiter
