Sinonimi: semiconductor diode | junction rectifier | crystal rectifier | rectifying tube | rectifying valve
A device that passes current in only one direction. A diode is usually a semiconductor. See the illustration. See also semiconductor.
Combination of a cold anode and a heated cathode (or the semiconductor equivalent, which incorporates a p–n junction). Either device allows the passage of direct current in one direction only, and so is commonly used in a rectifier to convert alternating current (AC) to direct current (DC).
