Boards in 1 GitHub repository, designed in KiCad, that use the STTH110 by STMicroelectronics (1 Independent 1.7V@1A 10uA@1kV 1A 1kV 20A 75ns DO-41 Fast Recovery / High Efficiency Diodes ROHS). See how each wires it, with its parts, size, README and files; the STTH110’s symbol, footprint and pinout are on its own page.
