Abstract

An electronic switch, in particularly a transistor, has at least one barrier layer extending between regions of different doping concentrations within a semiconductor and is characterized in that the barrier layer has at least one voltage limiting zone (Z) having a radius of curvature (R) less than or at most equal to the diffusion depth (x.sub.JB) of the diffused junction.
