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 | LED1_A | input | Channel 1 input LED anode (E1+). Drive with forward current IF = 5-30 mA (typ 7 mA); VF ≈ 1.2 V. Series resistor required per E1 supply voltage (e.g. 300 Ω @ 3.3 V, 600 Ω @ 5 V). |+| 2 | LED1_K | input | Channel 1 input LED cathode (E1-). Return path for channel 1 LED forward current. |+| 3 | LED2_A | input | Channel 2 input LED anode (E2+). Drive with forward current IF = 5-30 mA (typ 7 mA); VF ≈ 1.2 V. Independent from channel 1 (2 Form A / 2 input configuration). |+| 4 | LED2_K | input | Channel 2 input LED cathode (E2-). Return path for channel 2 LED forward current. |+| 5 | OUT2_A | passive | Channel 2 MOSFET output drain (IL2 / VL2). AC or DC load switching; polarity non-critical. Load rated 60 V max, 0.5 A continuous (1.5 A peak, 100 ms pulse), Ron ≈ 0.8 Ω typ. |+| 6 | OUT2_B | passive | Channel 2 MOSFET output drain (IL2 / VL2). Pairs with pin 5 as the channel-2 load switch; AC/DC capable due to back-to-back MOSFET topology. |+| 7 | OUT1_A | passive | Channel 1 MOSFET output drain (IL1 / VL1). AC or DC load switching; polarity non-critical. Load rated 60 V max, 0.5 A continuous, Ron ≈ 0.8 Ω typ. |+| 8 | OUT1_B | passive | Channel 1 MOSFET output drain (IL1 / VL1). Pairs with pin 7 as the channel-1 load switch; AC/DC capable due to back-to-back MOSFET topology. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | SUPSiC |+| Package | SOP-8 |+| Category | Optoisolators |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `GAQW212GS`++## CAD (KiCad official)++- Symbol: `GAQW212GS`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [SUPSiC datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8602996011904352256) (5 pp, sha256 `57949bd7a2206fb7`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
