The common thyristor solution used in higher current ac switching is two isolated SCR’s. The added hardware and packaging required to provide the needed isolated heat sinking in this configuration is a cost drawback. Triacs allow a single heat sink, but are limited by their thermal performance in current, blocking voltage, and higher frequency applications.
