BTA41-600BW 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 T1 of the triac (pin 1 per the page 1 pin drawing); the TO-3P package is insulated (2500 VRMS rated insulation voltage), and IT(RMS) is 40 A. |
| 2 | T2 | passive | Main terminal T2 of the triac (pin 2 per the page 1 pin drawing), with VDRM/VRRM of 600 V and IT(RMS) of 40 A. |
| 3 | G | input | Gate terminal (pin 3) that triggers the triac, with IGT max 50 mA in quadrants I-II-III, VGT max 1.3 V, and IGM peak gate current 8 A. |
