Title: Triac with gold diffused boundary

Abstract: Disclosed is a bidirectional triode thyristor pellet that comprises two current conductive regions and a gate region. Gold is diffused into the boundaries between the several regions to inhibit carrier migration thereacross and thus reduce turnoff time. Also disclosed is a method of fabricating the subject thyristor pellet that permits glass passivation thereof if desired.
