PC817X4NSZ2B from Sharp Microelectronics, 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 | input | Anode of the input LED; the datasheet rates forward current IF at 50 mA maximum, peak forward current IFM at 1 A (pulse width ≦100 μs, duty ratio 0.001), and reverse voltage VR at 6 V. |
| 2 | Cathode | passive | Cathode of the input LED, which is the return terminal for the LED drive current; the reverse voltage rating of the input LED is 6 V. |
| 3 | Emitter | passive | Emitter of the output phototransistor; the emitter-collector voltage VECO is rated at 6 V maximum. |
| 4 | Collector | passive | Collector of the output phototransistor; the collector-emitter voltage VCEO is rated at 80 V maximum and collector current Ic at 50 mA maximum. |
