In electronics, a diode is a two-terminal electronic component that conducts electric current in only one direction. The term usually refers to asemiconductor diode, the most common type today. This is a crystalline piece of semiconductor material connected to two electrical terminals.
The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction) while blocking current in the opposite direction (the reverse direction). Thus, the diode can be thought of as an electronic version of a check valve. This unidirectional behavior is called rectification, and is used to convert alternating current to direct current.
