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 | COM | passive | Common (main terminal 1, MT1) of the Triac. Reference terminal for OUT and for the gate drive. Typically tied to the low-side of the AC load or to the mains return in appliance/compressor drives. |+| 2 | OUT | passive | Output (main terminal 2, MT2) of the Triac; also electrically bonded to the TO-220AB heat-sink tab. Carries the switched AC load current (up to 10 A RMS, VDRM/VRRM = 700 V) and the clamped surge current during IEC 61000-4-5 events. |+| 3 | G | input | Gate trigger input. For the ACST1035-7, IGT ≤ 35 mA (quadrants I-II-III, VOUT = 12 V, RL = 33 Ω), VGT ≤ 1.0 V, IGM ≤ 1.6 A (tp = 20 µs). Drive via a series gate resistor from an MCU or gate driver referenced to COM. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | TO-220 |+| Category | Transistors/Thyristors |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `ACST1035-7TT`+- `ACST1035-7TFP`++## CAD (KiCad official)++- Symbol: `ACST1035-7T`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590408805684183040) (None pp, sha256 `38d92a3c09844f5e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
