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 | Anode | input | LED anode of the input-side GaAs infrared emitter. Drive with forward current IF (max 50 mA DC, 1000 mA pulsed 1 us); typical VF ~1.2 V at IF=20 mA. Use a series current-limiting resistor. |+| 2 | Cathode | input | LED cathode of the input-side infrared emitter. Reverse voltage rated to VR=6 V max. Return path for the LED drive current. |+| 3 | Emitter | output | Emitter of the output-side NPN silicon phototransistor. Typically tied to the output-side ground/reference. VECO breakdown 6 V max. |+| 4 | Collector | output | Collector of the output-side NPN phototransistor. Sinks collector current IC (max 50 mA) modulated by the LED photocurrent. BVCEO >= 80 V; VCE(sat) typ 0.1 V (max 0.2 V) at IF=20 mA, IC=1 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | AOTE |+| Package | DIP-4 |+| Category | Optoisolators |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `AT817C-FeH-DE-CuH-D`+- `AT817C-FeH-DE`+- `AT817C-FeH-DE-CuH-DE`+- `AT817C-FeH-DE-CuH-S`+- `AT817C-FeH-S`+- `AT817C-FeH-DE-CuH-M`+- `AT817C-FeH-M`++## CAD (KiCad official)++- Symbol: `AT817C-FeH-DE`+- 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:** [AOTE datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590921295477755904) (12 pp, sha256 `6b8be713aab0a028`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
