ABSTRACT:
The invention provides a silicon controlled rectifier having an anode and a cathode and including an NPN transistor and a PNP transistor. The NPN transistor has an emitter coupled to the cathode, a base and a collector. The PNP transistor has a base coupled to the NPN collector, an emitter coupled to the anode, a first collector coupled to the NPN base and a second collector coupled to the NPN collector.
