Abstract

Una disposición de circuito de protección contra sobretensiones, conectado entre un punto de un potencial fijo y un punto del circuito a proteger contra aumentos de tensión que superen un valor predeterminado con respecto a dicha masa, comprendiendo dicho circuito de protección, un transistor bipolar de unión lateral que tiene zonas de colector y de emisor separadas por una zona de base que forma parte de un sustrato semiconductor en el que está formado dicho transistor; estando cubiertas la unión de colector y la citada zona de base de dicho transistor por una capa aislante , estando separadas dichas zonas de colector y de emisor por dicha zona de base en una distancia que permite la acción sustancial del transistor cuando dicha unión de colector es polarizada en sentido inverso y la unión de emisor de dicho transistor está polarizada en sentido directo, un primer miembro conductor sobre dicha capa aislante en la posición de dicha unión de colector, estableciendo dicho primer miembro conductor contacto eléctrico con dicha área o zona de emisor, con dicho sustrato y con dicho punto de potencial fijo, y estableciendo un segundo miembro conductor contacto eléctrico con el citado punto del circuito a proteger y con dicha región de colector de dicho transistor.
