PC817C-S from UMW, in a SOP-4-2.54mm. 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 GaAs input emitter; the absolute maximum forward current is 50 mA and the reverse voltage is 6 V. |
| 2 | Cathode | passive | LED cathode of the GaAs input emitter; the absolute maximum forward current is 50 mA and the reverse voltage is 6 V. |
| 3 | Emitter | passive | Emitter of the NPN output transistor; the absolute maximum emitter-to-collector voltage VECO is 6 V. |
| 4 | Collector | passive | Collector of the NPN output transistor; the absolute maximum collector-emitter voltage VCEO is 35 V, collector current IC is 50 mA, and output power PC is 150 mW. |
