AT215-CuH-S from AOTE, in a SSOP-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Anode | passive | LED anode of the input emitter; recommended forward current IF is 5 to 15 mA (absolute max 50 mA, reverse voltage max 6 V). |
| 2 | Cathode | passive | LED cathode of the input emitter, returned to the input-side ground/drive return. |
| 3 | Emitter | passive | Emitter of the Darlington phototransistor output; emitter-collector voltage max 7 V. |
| 4 | Collector | passive | Collector of the Darlington phototransistor output; VCEO max 40 V and collector current IC max 100 mA. |

- Symbol:
AT215-CuH-S - Footprint:
Package_SO:SSOP-4_4.4x2.6mm_P1.27mm - 3D model: SSOP-4, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
