PDF of 166 KB for the 40TPS16, catalogued under schematics though it is a part datasheet. The 40TPS designation corresponds to a phase-control thyristor (SCR) series in a TO-247 style package, with the trailing number indicating the voltage class. The document shows gate, anode and cathode pin positions, trigger current and surge ratings. Use it when testing an SCR in soft-start or inrush limiting circuits and when sourcing a replacement with at least the same voltage and current rating.
