BT136D from FUXINSEMI, in a TO-252. 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 1 (A1), the triac's lower-side main terminal per the circuit diagram on page 1; the number is assumed, not printed. |
| 2 | A2 | passive | Main terminal 2 (A2), the center lead, which the datasheet also shows connected to the mounting tab; the number is assumed, not printed. |
| 3 | G | input | Gate trigger input (G); triggers with IGT max 10 mA in quadrants I-II-III and 25 mA in quadrant IV, and VGT max 1.3 V; the number is assumed, not printed. |
