BTB08-800TWRG 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, the reference terminal for gate triggering (the datasheet gives VGT, IGT and IH with A2 referenced to A1). |
| 2 | A2 | passive | Main terminal A2, which is also connected to the metal tab on the non-insulated TO-220AB. It carries up to 8 A rms on-state current and is rated for 800 V VDRM/VRRM on this BTB08-800TW part. |
| 3 | G | input | Gate trigger input; the TW version triggers with IGT max 5 mA (VD = 12 V, RL = 30 Ω) and VGT max 1.2 V in quadrants I-II-III. |
