a semiconductor device containing one p-n junction, used in circuits for converting alternating current to direct current
More formal name: semiconductor diode
2.
the earliest and simplest type of electronic valve having two electrodes, an anode and a cathode, between which a current can flow only in one direction. It was formerly widely used as a rectifier and detector but has now been replaced in most electrical circuits by the more efficient and reliable semiconductor diode
