Claim 17:
18. The apparatus of claim 16, wherein the lateral SCR is a first lateral SCR, the PNP transistor is a first PNP transistor, the NPN transistor is a first NPN transistor, and the isolation trench is a first isolation trench, the apparatus further comprising a second lateral SCR including:
a third p-type implant disposed in the semiconductor layer, the third p-type implant being included in an emitter of a second PNP transistor, the second PNP transistor being included in the second lateral SCR;
a third n-type implant disposed in the semiconductor layer, the third n-type implant being included in a base of the second PNP transistor and a collector of a second NPN transistor, the second NPN transistor being included in the second lateral SCR;
a fourth p-type implant disposed in the semiconductor layer, the fourth p-type implant being included in a collector of the second PNP transistor and a base of the second NPN transistor;
a fourth n-type implant disposed in the semiconductor layer, the fourth n-type implant being included in an emitter of the second NPN transistor; and
a second isolation trench disposed in the semiconductor layer in a base region of the second PNP transistor and a collector region of the second NPN transistor, at least a portion of the semiconductor layer being included in the base region of the second PNP transistor and the collector region of the second NPN transistor.
