PC817A from GOODWORK, 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 | Anode of the GaAs input LED (pin-1 dot marked Anode), with absolute maximum forward current IF 50 mA and reverse voltage VR 6 V. |
| 2 | Cathode | passive | Cathode of the GaAs input LED, with typical forward voltage VF 1.20 V (max 1.40 V) at IF=20 mA. |
| 3 | Emitter | passive | Emitter of the NPN phototransistor output, with VECO max 6 V and collector current IC max 50 mA. |
| 4 | Collector | passive | Collector of the NPN phototransistor output, with VCEO max 35 V and collector current IC max 50 mA. |
