Abstract: A transistor includes a quasi-intrinsic region of a first conductivity type that is covered with an insulated gate. The quasi-intrinsic region extends between two first doped regions of a second conductivity type. A main electrode is provided on each of the two first doped regions. A second doped region of a second conductivity type is position in contact with the quasi-intrinsic region, but is electrically and physically separated by a distance from the two first doped regions. A control electrode is provided on the second doped region.
