Abstract: Electronic device, comprising: a semiconductor body having a surface, an electrical conductivity P and a first doping value; at least one gate region on the surface; one or more source regions, having a second electrical conductivity N, extending in the semiconductor body at the surface and at a first side of the gate region; and at least one body contact region, of P+ type, extending in the semiconductor body at the surface and at the first side of the gate region 22. The first gate region has the shape of a stripe with main extension along a first direction. The first body contact region has a tapered shape along said first direction. The one or more source regions are adjacent to, and at least partially surround, the first body contact region.
