English

Subject field(s)
  • Semiconductors (Electronics)
DEF

A silicon diode that has a high ratio of reverse-to-forward resistance until avalanche breakdown occurs. After breakdown the voltage drop across the diode is essentially constant and is independent of the current.

CONT

Used for voltage regulating and voltage limiting. Originally called zener diode, before it was found that the Zener effect had no significant role in the operation of diodes of this type.

OBS

Zener diode: term officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Semi-conducteurs (Électronique)
DEF

Diode à semi-conducteurs qui présente pour de faibles tensions inverses (-5 V -20 V) un phénomène de claquage par avalanche.

CONT

Ce claquage se fait à tension presque constante, il n'est pas destructif. Les diodes Zener sont employées comme régulatrices, ou comme référence de tension.

OBS

diode Zener; diode de Zener : termes uniformisés par le Comité du projet de lexiques (Nouveau-Brunswick).
