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
