Abstract:
A MOSFET component comprising:a lightly n-type doped region;a p-type trough incorporated into the lightly n-type doped region;a heavily n-type doped source region situated in the p-type trough;a parasitic transistor, the source region being an emitter of the transistor, the p-type trough being a base of the transistor, the n-type doped region being a collector of the transistor, the transistor having a base-emitter link;a pass-under resistor formed by a p-type region of the p-type trough beneath the source region; anda p-type conductive path parallel-connected to the base-emitter link of the transistor, the conductive path having a heavily p-type doped auxiliary region parallel-connected to the pass-under resistor, the heavily p-type doped auxiliary region being incorporated in the p-type trough, wherein:the source region and the heavily p-type doped auxiliary region are incorporated in the p-type through in an alternating sequence, andthe source region and the heavily p-type doped auxiliary region extend from a first side of the p-type trough to a channel region on a second side of the p-type trough.
