BTA12-800BRG from STMicroelectronics, in a TO-220AB. 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 of the triac, the reference for gate and A2 polarities, rated for 12 A IT(RMS) (Tc = 90 °C, TO-220AB Ins.). |
| 2 | A2 | passive | Main terminal A2 of the triac, rated for VDRM/VRRM of 800 V on the BTA12-800B and 12 A IT(RMS), and also shown on the tab, which is insulated (2500 VRMS). |
| 3 | G | input | Gate trigger input; IGT max 50 mA (quadrants I-II-III) and 100 mA (quadrant IV) for the B standard version at VD = 12 V, RL = 30 Ω, with VGT max 1.3 V. |
