ACST310-8B from STMicroelectronics, in a DPAK. 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 | COM | passive | Common main terminal (triac anode/reference) of the AC switch; OUT is specified for both polarities referenced to this pin, with IT(RMS) 3 A at Tc = 112 °C. |
| 2 | OUT | passive | Output main terminal of the AC switch, also the metal tab, blocking VDRM/VRRM of 800 V with a minimum clamping voltage VCL of 850 V. |
| 3 | G | input | Gate trigger input driven directly by a microcontroller through a resistor, with IGT max. 10 mA and VGT max. 1.1 V in quadrants I, II and III. |
