BTA08-600SWRG

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

BTA08-600SWRG from STMicroelectronics, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Main terminal 1 (MT1/A1), one of the two power (load-current) terminals of the triac and the reference point to which gate trigger voltage VGT and current IGT are specified.
2 A2 passive Main terminal 2 (MT2/A2), the second power (load-current) terminal, internally connected to the package mounting tab; for this BTA08 (Ins.) TO-220AB Ins. variant the tab is electrically isolated and rated at 2500 VRMS insulation, with Rth(j-c) = 2.5 degC/W.
3 G input Gate control terminal; applying a gate current IGT referenced to A1 (5 mA min for the SW logic-level sensitivity of this part, VGT max 1.2 V) triggers the triac into conduction.
