Boards in 2 GitHub repositories, designed in KiCad, that use the 2SCR587D3TL1 by ROHM Semiconductor (1 NPN 10W 120 120V 120mV 1uA 250MHz 3A 6V NPN TO-252 Bipolar (BJT) ROHS). See how each wires it, with its parts, size, README and files; the 2SCR587D3TL1’s symbol, footprint and pinout are on its own page.
