T1635H-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 | A1 | passive | Main terminal 1 (reference terminal for gate triggering, anode 1). |
| 2 | A2 | passive | Main terminal 2 (anode 2), internally connected to the mounting tab which is electrically isolated in this insulated TO-220AB package rated for 2.5 kV RMS insulation. |
| 3 | G | input | Gate trigger input; triggers the triac in all three quadrants, with IGT max 35 mA and VGT max 1.3 V, peak gate current up to 4 A and average gate power dissipation up to 1 W. |
