Abstract

L'invention concerne les éléments de commutation photosensibles. Un élément de commutation photosensible comprend essentiellement un transistor à effet de champ 3, qui n'est pas nécessairement lui-même photosensible, un réseau de photodiodes 7 qui est en couplage optique avec une source lumineuse 5, et qui commute l'état de conduction du transistor, et une résistance R2 qui est branchée en parallèle sur le réseau 7 pour améliorer le temps de commutation. Application aux isolateurs opto-électroniques.The invention relates to photosensitive switching elements. A photosensitive switching element essentially comprises a field effect transistor 3, which is not necessarily itself photosensitive, an array of photodiodes 7 which is in optical coupling with a light source 5, and which switches the conduction state of the transistor, and a resistor R2 which is connected in parallel to the network 7 to improve the switching time. Application to opto-electronic isolators.
