BT131-600-MS

MSKSEMI · TRIACs · SOT-89

BT131-600-MS from MSKSEMI, in a SOT-89. 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 T1 passive Main terminal 1 (T1) of the TRIAC; the datasheet gives only its pin assignment, with the device rated for 600 V repetitive peak off-state voltage (VDRM, VRRM) and 2 A RMS on-state current (IT(RMS)).
2 T2 passive Main terminal 2 (T2) of the TRIAC; the datasheet gives only its pin assignment, with a non-repetitive peak on-state current limit of 20 A (ITSM) and a repetitive rate of rise of on-state current limit of 50 A/µs for quadrants I to III and 10 A/µs for quadrant IV.
3 G input Gate (G) trigger terminal; the datasheet limits peak gate current to 1.8 A (IGM), peak gate power to 4 W (PGM), average gate power to 0.5 W (PG(AV)), and gate trigger current IGT to 25 mA maximum in quadrant IV.
