Abstract:
A structure integrated in a chip of semiconductor material of first conductivity type and comprising:first and second regions of second conductivity type extending into the chip of semiconductor material from a surface thereof and forming first and second junctions; andmeans for reducing an injection of current from the first region to the second region when the first junction is polarized for transmission, said means for reducing an injection current comprisinga third region of second conductivity type extending from the surface into a portion of the chip of semiconductor material disposed between the first region and the second region, and electrical connection means extending between the first region and third region,a fourth region of first conductivity type extending from the surface into the third region,electrical connection means between the fourth region and the second region; anda power transistor for controlling an inductive load and having its collector region as the chip of semiconductor material, and wherein the first junction defines a recirculating diode associated with the power transistor.
