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. |
