See also: Diode
diode (plural diodes)
- An electronic device that allows current to flow in one direction only; used chiefly as a rectifier.
1919 April 18, William Eccles, Electrician, page 475:
- I propose to give the name diode to a tube with two electrodes.
1949, Samuel Silver, Microwave Antenna Theory and Design, page 593:
- If a crystal or a diode is used, the amplifier-voltmeter combination may be used with an amplitude-modulated source; or with a c-w source, the detector may be connected to a microammeter or galvanometer as an indicating device.
2005, Robert Diffenderfer, Electronic Devices: Systems and Applications, page 69:
- In this circuit when the diode is forward biased, the voltage across the diode remains fairly close to the diode's barrier potential.
