Like any semiconductor device, the zener diode is sensitive to temperature. Excessive temperature will destroy a zener diode, and because it both drops voltage and conducts current, it produces its own heat in accordance with Joule's Law (P=IE).

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

The second of the diodes is a zener diode which are fairly popular for the voltage regulation of low current power supplies. Whilst it is possible to obtain high current zener diodes, most regulation today is done electronically with the use of dedicated integrated circuits and pass transistors.
