T435-700B-TR from STMicroelectronics, in a DPAK. 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 | A1 | passive | Main terminal 1 (MT1); AC power terminal, reference terminal for gate trigger current IGT and gate voltage VGT measurements. |
| 2 | A2 | passive | Main terminal 2 (MT2); AC power terminal, internally connected to the DPAK metal tab used for heat dissipation (Rth(j-c) = 2.6 °C/W). |
| 3 | G | input | Gate; trigger input requiring IGT = 5 to 35 mA (T435, all quadrants) at VGT max 1.3 V to turn on the triac; max peak gate current IGM = 4 A, average gate power dissipation PG(AV) = 1 W. |
