STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB

BTA16-800BWRG from STMicroelectronics, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 bidirectional Main terminal (Anode 1) of the triac; conducts up to 16 A RMS at 100°C case temperature when triggered via the gate terminal.
2 A2 bidirectional Main terminal (Anode 2) of the triac; conducts up to 16 A RMS at 100°C case temperature when triggered via the gate terminal.
3 G input Gate control input terminal; triggers the triac with maximum gate trigger current of 50 mA and maximum gate threshold voltage of 1.3 V.
