COMFET switch and method

The performance of COMFET-based electrical switches may be improved by connecting a MOSFET substantially in parallel with the COMFET. In a monolithic embodiment, a MOSFET drain region may be added to a surface of a COMFET and shorted to the emitter region of the COMFET. The invention decreases the t...

Zusammenfassung:The performance of COMFET-based electrical switches may be improved by connecting a MOSFET substantially in parallel with the COMFET. In a monolithic embodiment, a MOSFET drain region may be added to a surface of a COMFET and shorted to the emitter region of the COMFET. The invention decreases the turn-off time of the COMFET, reduces the discontinuity at current direction reversal and increases the latch-up current of a semiconductor switch.
