A semiconductor diode is thus commonly used as a noise source by passing a particular DC current through it.
22.
Transistors and semiconductor diodes were soldered to the outside of the Q-pac encapsulation for ease of cooling and replacement.
23.
A common semiconductor diode, such as a series, which could be connected to an oscilloscope as a quick diagnostic.
24.
For information about semiconductor detectors in radio, see Diode # Semiconductor diodes, rectifier, detector ( radio ) and cat's-whisker detector.
25.
They were replaced in power supplies beginning in the 1940s by selenium rectifiers and then by semiconductor diodes by the 1960s.
26.
A semiconductor diode always has an exponential relationship of current to applied voltage ( neglecting the small reverse leakage current ).
27.
It was used for battery chargers and similar applications from the 1920s until lower-cost metal rectifiers, and later semiconductor diodes, supplanted it.
28.
Semiconductor diodes have multiple uses including rectification of alternating current to direct current, detection of radio signals, emitting light and detecting light.
29.
A semiconductor diode's behavior in a circuit is given by its current voltage characteristic, or I V graph ( see graph below ).
30.
The earliest metal semiconductor diodes in electronics application occurred around 1900, when the evaporated onto large metal substrates to form the rectifying diodes.
