Random House Webster's College Dictionary
(or Ze′ner ) di`ode
a semiconductor diode across which the reverse voltage remains almost constant over a wide range of currents, used esp. to regulate voltage.
Origin of zener diode:
1955–60; after U.S. physicist Clarence Melvin Zener (born 1905)
A semiconductor junction device through which current flows normally in the forward direction, and in the reverse direction if a large voltage is applied.
Origin: From Clarence Zener, American physicist.
A Zener diode is a diode which allows current to flow in the forward direction in the same manner as an ideal diode, but will also permit it to flow in the reverse direction when the voltage is above a certain value known as the breakdown voltage, "zener knee voltage", "zener voltage" or "avalanche point". The device was named after Clarence Zener, who discovered this electrical property. Many diodes described as "zener" diodes rely instead on avalanche breakdown as the mechanism. Both types are used. Common applications include providing a reference voltage for voltage regulators, or to protect other semiconductor devices from momentary voltage pulses.
