PC817C-S

UMW · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

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.
