    What destroys ICs downstream after the SCR shorts to VSS?

    Is it a current surge?

    Or reverse voltage?

    EDIT: Added NTC for current surge protection at output, and extra TVS up front (we get a lot of power surges here, hydro lines are not the most stable with so many trees).

    EDIT SOME MORE: In keeping with Tim The Toolman's philosophy of "cause we can", I added a Varistor on output.
