Abstract

Perfeccionamientos en interruptores con un transistor de efecto de campo acoplado óptimamente, del tipo que comprende un transistor de efecto de campo que tiene un electrodo fuente, un electrodo puerta y un electrodo de drenaje, conectándose los electrodos de fuente y un electrodo de drenaje, conectándose los electrodos de fuente y de drenaje a un circuito eléctrico de salida, y un dispositivo de control acoplado óptimamente a una fuente luminosa para controlar la corriente a través del transistor de efecto de campo, caracterizados porque el dispositivo de control comprende una formación de fotodiodos conectada entre los electrodos puerta y fuente y que tiene por lo menos un fotodiodo, interconectándose en serie entre sí los fotodiodos cuando se encuentran presentes en un número de más de 1, eligiéndose el número de fotodiodos en la formación para producir, al iluminarse la fuente luminosa, un voltaje suficiente para controlar la corriente a través del FET.
