DIODE THAT ALLOWS CURRENT TO FLOW IN THE REVERSE DIRECTION AT A SPECIFIC VOLTAGE
Zener Diode; Stabilitron; Zehner diode; Xener diode; Zener diodes
A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" when a certain set reverse voltage, known as the Zener voltage, is reached.

Zener Diode; Stabilitron; Zehner diode; Xener diode; Zener diodes
['zi:n?]
¦ noun Electronics a semiconductor diode in which at a critical reverse voltage a large reverse current can flow.
Origin
1950s: named after the American physicist Clarence M. Zener.
Zener effect         
  • I-V curve]] for a diode showing avalanche and Zener breakdown.
TYPE OF ELECTRICAL BREAKDOWN
Zener breakdown; Zener tunneling
In electronics, the Zener effect (employed most notably in the appropriately named Zener diode) is a type of electrical breakdown, discovered by Clarence Melvin Zener. It occurs in a reverse biased p-n diode when the electric field enables tunneling of electrons from the valence to the conduction band of a semiconductor, leading to numerous free minority carriers which suddenly increase the reverse current.
