BTA41-800BW

FUXINSEMI · TRIACs · TO-3P

BTA41-800BW from FUXINSEMI, 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 A1 passive Main terminal A1 (cathode-side terminal of the triac), carrying up to 40 A RMS on-state current (IT(RMS)) and the reference terminal for gate triggering.
2 A2 passive Main terminal A2 (anode-side terminal of the triac) which blocks VDRM/VRRM of 800 V for the BTA41-800BW and carries up to 40 A RMS; the insulated package tab is not connected to it.
3 G input Gate trigger input with IGT max 50 mA and VGT max 1.3 V at VD=12 V, RL=33 Ω in quadrants I-II-III, peak gate current IGM 4 A.
