zener diode

Definitions

General Science

• noun a semiconductor-based device used as a voltage regulator because the voltage across it is independent of the current through it

Cars & Driving

• noun
  (written as Zener diode)
  a voltage regulator diode in electronic ignition and alternator output circuits

Electronics

• (written as Zener diode)
  A pn-junction diode with high doping on both sides of the boundary, and which utilizes Zener breakdown to provide a given maximum voltage across it. A Zener diode has a breakdown voltage of a few volts, up to about six, while an avalanche diode usually has a much higher breakdown voltage, sometime several hundred volts. Used, for instance, as a voltage-regulator diode.
