FOC-817D

Foshan NationStar Optoelectronics · Transistor, Photovoltaic Output Optoisolators · DIP-4

FOC-817D from Foshan NationStar Optoelectronics, in a DIP-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 Positive terminal of the internal infrared LED input, rated for a forward current IF of 50 mA maximum and a reverse voltage VR of 6 V maximum.
2 Cathode passive Negative terminal of the internal infrared LED input, with the LED reverse voltage limited to VR = 6 V maximum per the absolute maximum ratings.
3 Emitter passive Emitter of the internal phototransistor output, with an emitter-collector voltage VECO rated at 6 V.
4 Collector passive Collector of the internal phototransistor output, rated for a collector-emitter voltage VCEO of 80 V and a collector current IC of 50 mA maximum.
