T1235-600G-TR from STMicroelectronics, in a D2PAK. 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 | A2 | passive | Main Terminal 2 (MT2); also electrically connected to the package mounting tab. Rated for IT(RMS)=12 A (full sine wave, Tc=105°C), non-repetitive surge ITSM=120 A (50 Hz)/126 A (60 Hz), and blocking voltage VDRM/VRRM=600 V for this 600 V-rated device; dV/dt and dV/dt(c) referenced to A1 per datasheet Table 3. |
| 2 | G | input | Gate trigger input; for the T1235 (35 mA sensitivity) grade, IGT max = 35 mA, VGT max = 1.3 V, VGD min = 0.2 V; absolute maximum peak gate current IGM = 4 A (tp=20 µs) and average gate power dissipation PG(AV) = 1 W at Tj=125°C. |
| 3 | A1 | passive | Main Terminal 1 (MT1), reference terminal for gate and A2 voltage/current polarity specifications; shares the same IT(RMS)=12 A, ITSM and VDRM/VRRM=600 V ratings as A2 since it is the second load-current-carrying terminal of the triac. |
