PC3H7B 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 | input | LED anode of the input emitter; the datasheet limits forward current IF to 50 (printed as 'A', likely mA), reverse voltage VR to 6 V, and peak pulse forward current IFP to 1000 (1 µs pulse, printed as 'A'). |
| 2 | Cathode | passive | LED cathode of the input emitter, returning the forward current; the same input ratings apply (IF 50, VR 6 V, IFP 1000 for 1 µs pulses, units as printed). |
| 3 | Emitter | passive | Phototransistor emitter on the output side; the datasheet gives emitter-collector voltage VECO 7 V maximum and BVECO of at least 7 V at IE=0.01mA. |
| 4 | Collector | passive | Phototransistor collector on the output side; the datasheet gives collector-emitter voltage VCEO 80 V maximum, collector current IC 50 (printed as 'A', likely mA), and total power Ptot 200 (printed as 'W'). |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
