1. (Electrical Engineering) a semiconductor device containing one p-n junction, used in circuits for converting alternating current to direct current. More formal name: semiconductor diode
2. (Electrical Engineering) 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
[C20: from di-1 + -ode2]

a device, as a two-element electron tube or a semiconductor, through which current can pass freely in only one direction.

The heated cathode generates a cloud of electrons that are attracted by the anode, causing a current to flow from the cathode to the anode. Because the anode cannot generate electrons of its own, the current cannot flow in the opposite direction.
An electron tube or a semiconductor that allows current to flow in one direction only. Diodes can be used to convert AC currents into DC currents.
