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. |
