Claim Text:
1. An electronic device, comprising: a first device terminal; a second device terminal; a first thyristor and a second thyristor reverse-connected between the first and second device terminals, each thyristor including an anode, a cathode, an NPN bipolar transistor and a PNP bipolar transistor, each bipolar transistor having an emitter, a base, and a collector; a first MOS transistor and a second MOS transistor coupled between conduction electrodes of the NPN bipolar transistors of the first and second thyristors; a third MOS transistor coupled between emitters of the NPN bipolar transistors of the first and second thyristors; a fourth MOS transistor coupled between bases of the PNP bipolar transistors of the first and second thyristors; a gate region common to the first, second, third and fourth MOS transistors; and a common semiconductor region, wherein the first, second, third and fourth MOS transistors are formed within the common semiconductor region.
