BTA08-800BWRG 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 1 (MT1); one side of the bidirectional AC conduction path; IT(RMS) 8 A max at Tc = 100 °C (TO-220AB Ins.), VDRM/VRRM 800 V, non-repetitive surge ITSM 80 A (50 Hz, 20 ms). |
| 2 | A2 | passive | Main Terminal 2 (MT2); opposite side of the bidirectional AC conduction path; internally connected to the heatsink tab which is electrically isolated from the mounting surface via ceramic pad rated 2500 VRMS (BTA insulated series), VDRM/VRRM 800 V. |
| 3 | G | input | Gate trigger input; IGT max 50 mA (Q1-Q3, VD = 12 V, RL = 33 Ω), VGT max 1.3 V, IGM peak 4 A (tp ≤ 20 µs, Tj = 125 °C), average gate power dissipation PG(AV) max 1 W at Tj = 125 °C. |
