Zener diode

A diode designed to conduct current when reverse biased with a specific threshold voltage (a.k.a. its avalanche point). Because of this, Zener diodes can be used by themselves as voltage-sensitive switches, or in series with a current-limiting resistor to provide voltage regulation.

See also the diode discussion here. Meanwhile, AMS has a good zener diode tutorial page here.

For diode selection and comparison information, see the diode section of the BEAM Reference Library's BEAM Pieces collection.
