T1625T-8I 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 | G | input | Gate trigger electrode; trigger current 25 mA (quadrants I-III) or 50 mA (quadrant IV) required at VD = 12 V with RL = 30 Ω. |
| 2 | A2 | bidirectional | Main terminal (anode 2); conducts main current bidirectionally when triggered via gate; on-state voltage 1.55 V max at IT = 22.6 A. |
| 3 | A1 | bidirectional | Main terminal (anode 1); conducts main current bidirectionally when triggered via gate; serves as reference terminal for A2 voltage characterization. |
