jonction collecteur-base

collector-base junction

électronique et électrotechnique - iate.europa.eu

Lorsqu'on inverse cette tension, la jonction émetteur-base subit une polarisation inverse et la jonction collecteur-base est désactivée.

When the supply voltage is reversed, the emitter-base junction is reverse biased and the collector-base junction is turned off.

La jonction collecteur-base est toujours soumise à une tension inverse.

The collector-base junction is always in reverse bias.

général - CCMatrix (Wikipedia + CommonCrawl)

Le dopage additionnel du collecteur est réalisé le long d'une jonction collecteur-base sous la base proprement dite (76A) pour créer une zone collectrice spéciale (88), espacée latéralement de la région de couche d'oxyde (64).

The extra collector doping is provided along collector-base junction below the intrinsic base (76A) to create a special collector zone (88) spaced laterally apart from the field-isolation region (64).
