ABSTRACT:
The present invention is directed to a four-region solid-state switching device whose topology readily links itself to light activation. Anode and cathode emitter regions of the device are disposed in the same surface of the device. Both base regions are exposed on a mesa portion disposed between the anode and cathode regions. The topology of the device is such that current flows across the device rather than through the device and light is introduced through the base regions perpendicular to the direction of current flow.
