Main » TERM » D » diode
An electric component that conducts electric current in only one direction, functioning as a one-way valve. Diodes typically are made from
semiconductor materials such as
silicon, germanium or selenium and are uses as voltage regulators, signal rectifiers, oscillators and signal
modulators/demodulators.
In computer equipment, diodes are commonly used to emit light by passing a current through it, as in light emitting diodes (LEDs).
