Abstract

L'invention concerne les dipôles à transistor. Elle se rapporte à un dipôle ayant un transistor 1 destiné à commuter lorsqu'une différence de potentiels appliquée au circuit collecteur-émetteur du transistor dépasse une valeur prédéterminée. Un circuit 2 de réaction à seuil est destiné à interrompre le courant de base transmis au transistor 1 lorsque la différence de potentiels dépasse la valeur prédéterminée. Application aux étages de puissance des amplificateurs électroniques.
