Drive with forward current IF = 5-10 mA (recommended); VF ≈ 1.14 V typ, 1.5 V max at IF = 5 mA. Absolute-max IF = 50 mA continuous, 1 A peak (IFP), 5 V reverse (VR). |+| 2 | CATHODE | input | LED cathode of the input opto-coupler; return path for the drive current supplied at pin 1. |+| 3 | LOAD1 | passive | Output MOSFET terminal (drain of one of the back-to-back output FETs). Interchangeable with pin 4 for AC or DC loads. Rated 400 V peak load voltage (VL), 120 mA continuous / 300 mA peak load current (IL/Ipeak), on-resistance Ron = 30 Ω typ (50 Ω max) with IF = 5 mA, off-state leakage <1 µA. |+| 4 | LOAD2 | passive | Output MOSFET terminal (drain of the other back-to-back output FET). Interchangeable with pin 3. Same ratings: 400 V peak VL, 120 mA IL, Ron = 30 Ω typ. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | OCIC |+| Package | DIP-4 |+| Category | Optoisolators |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `CYAQW214D4`+- `CYAQW214D4S4`+- `CYAQW214D4EH`+- `CYAQW214D4EHAX`++## CAD (KiCad official)++- Symbol: `CYAQW214D4`+- Footprint: `Package_DIP:DIP-4_W7.62mm`+- 3D model: DIP-4 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [OCIC datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590922397006438400) (None pp, sha256 `54a2ff830d345d9a`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
