ABSTRACT:
A power transistor incorporating a constant-voltage diode maintains the breakdown voltage of the constant-voltage diode at a specified level and prevents local breakdown of an insulating film located between an A1 field plate electrode and a base region of the transistor by spacing the A1 field plate electrode located on a collector region by a distance "d" from the base region.
