TPDV1240RG from STMicroelectronics, in a TO-3P-3. 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 of the triac, the reference electrode for A2 voltage and gate; insulated tab is isolated to 2,500 V rms from A1, A2 and gate. |
| 2 | A2 | passive | Main terminal A2 of the triac, blocking up to 1200 V (VDRM/VRRM) for TPDV1240RG and carrying 40 A rms on-state current at Tc = 75 °C. |
| 3 | G | input | Gate trigger terminal, IGT max 200 mA and VGT max 1.5 V (VD = 12 V DC, RL = 33 Ω), with peak gate current 8 A for tp = 20 µs. |
