diode (dÄ«'Åd') An electrical device with two active terminals, an anode and a cathode, through which current passes more easily in one direction (from anode to cathode) than in the reverse direction. Diodes have many uses, including conversion of AC power to DC power, and the decoding of audio-frequency signals from radio signals.
The diode is an uncontrolled device, and is capable on conducting current in one direction only. With power electronics it is used as a rectifier, or as a protection device with switching circuits. In practice we need to consider the turn-on and turn-off characteristics.
