I am working on a 24volt 10amp Battery Charger and trying locate a S1070W SCR. I need this or another one of similar value that would work in the control part of the circuit. Digikey didn't have it or a replacement. Mouser listed it as a non stocked item and they said it's not available from manufacturer. Maybe will have to come up with a different control circuit. From what I could find it was made by Teccor and Littelfuse.
