SCR Wiring

The SCR is a polarized device in the same sense that diodes are polarized. It only works in one orientation, so it seems useful to document how it was connected.

SCR Wiring

The diagram below is provided for the convenience of hobbyists using stud-type SCRs. Check your datasheet for your own SCR wiring!
