T1635T-8I from STMicroelectronics, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate trigger input terminal for controlling triac conduction; gate trigger current IGT = 1.75-35 mA, gate trigger voltage VGT max = 1.3 V (VD = 12 V, RL = 30 Ω, Tj = 25°C) |
| 2 | A2 | bidirectional | Anode 2 main current terminal; on-state rms current IT(RMS) = 16 A at Tc = 108°C (full sine wave), repetitive peak off-state voltage VDRM/VRRM = 800 V at Tj = 125°C |
| 3 | A1 | bidirectional | Anode 1 main current terminal; on-state rms current IT(RMS) = 16 A at Tc = 108°C (full sine wave), repetitive peak off-state voltage VDRM/VRRM = 800 V at Tj = 125°C |
