DIODE

A diode only blocks current in the reverse direction while the reverse voltage. Is with in a limited reange otherwise reverse barrier breaks and the voltage at which this break down occurs is called reverse breakdown voltage the diode acts as a value in the electronic and electrical circuits TYPES OF DIODE (1) ZENER DIODE (2) P-N JUNCTION DIODE (3) TUNNEL DIODE (4) VARACTOR DIODE (5) SCHOTTKY DIODE (6) PHOTO DIODE (7) PIN DIODE (8) LAZER DIODE (9) AVALAN CHE DIODE (10) LIGHT EMITTING DIODE
