Noun

diode (plural diodes)

1. 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^[1], 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^[2], 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.
