ze·ner diodeor Ze·ner diode (zē′nər)
A silicon semiconductor device used as a voltage regulator because of its ability to maintain an almost constant voltage with a wide range of currents.
[After Clarence Melvin Zener (1905-1993), American physicist.]
(Electrical Engineering) a semiconductor diode that exhibits a sharp increase in reverse current at a well-defined reverse voltage: used as a voltage regulator
[C20: named after C. M. Zener (1905–93), US physicist]
(or Ze′ner) di`ode(ˈzi nər)
a semiconductor diode across which the reverse voltage remains almost constant over a wide range of currents, used esp. to regulate voltage.
[1955–60; after U.S. physicist Clarence Melvin Zener (born 1905)]
