BTA41-1200BW

KTP · TRIACs · TO-3P

BTA41-1200BW from KTP, in a TO-3P. 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 of the triac, which carries the on-state current up to IT(RMS) 40 A (TC≤81℃).
2 T2 passive Main terminal 2 of the triac, with repetitive peak off-state and reverse voltage VDRM/VRRM of 1200 V.
3 G input Gate trigger input, with IGT max 50 mA and VGT max 1.3 V in quadrants I-II-III (VD=12V, RL=33Ω) and peak gate current IGM 8 A.
