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 | passive | LED anode (input side). Forward current IF up to 50 mA continuous, 1000 mA peak (1 µs pulse); VF typ 1.2 V / max 1.4 V at IF=20 mA. Drive through a current-limit resistor; keep reverse voltage below VR=6 V. |+| 2 | CATHODE | passive | LED cathode (input side). Return terminal for the infrared emitter; typically tied to input-side ground/return of the drive circuit. |+| 3 | EMITTER | passive | Phototransistor emitter (output side). Galvanically isolated from the LED side (VISO > 5000 Vrms, 1 min). Usually tied to output-side ground/return. |+| 4 | COLLECTOR | passive | Phototransistor collector (output side). Maximum IC=50 mA, VCEO=80 V, PC=150 mW. Dark current ICEO ≤ 100 nA at VCE=20 V. Current transfer ratio 130%-260% (bin B) at IF=5 mA, VCE=5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | AOTE |+| Package | DIP-4 |+| Category | Optoisolators |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `AT817B-FeH-DED`+- `AT817B-FeH-DEM`+- `AT817B-FeH-DES`++## CAD (KiCad official)++- Symbol: `AT817B-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/8590921295544729600) (12 pp, sha256 `29c7ba82cd4372ed`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
