HT-817-D-F from HENGTUO ELECTRONICS, 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 | LED anode input; forward current is rated 50 mA max (VF 1.2 V typ, 1.4 V max at IF=20 mA) and pins 1 and 2 are the input side isolated from pins 3 and 4 by 5000 Vrms. |
| 2 | Cathode | passive | LED cathode input; reverse voltage is limited to 6 V and peak forward current to 1 A (100 µs pulse, 100 Hz). |
| 3 | Emitter | passive | Phototransistor emitter output; emitter-collector voltage is limited to 6 V. |
| 4 | Collector | passive | Phototransistor collector output; collector-emitter voltage is rated 80 V max and collector current 50 mA max. |
