FODM2705R2 from onsemi, in a SOP-4-2.54mm. 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 | Infrared emitter anode; on the FODM2705 this is one of two LEDs connected in inverse parallel for AC input, with continuous forward current limited to 50 mA (avg) and peak forward current of 1 A (1 µs pulse, 300 pps). |
| 2 | CATHODE | passive | Infrared emitter cathode; on the FODM2705 this is the other terminal of the inverse-parallel LED pair for AC input, with the 6 V reverse voltage rating of the emitter applying. |
| 3 | EMITTER | passive | Phototransistor emitter, rated for an emitter-collector voltage (VECO) of 6 V maximum. |
| 4 | COLLECTOR | passive | Phototransistor collector, rated for 80 mA continuous collector current and a collector-emitter voltage (VCEO) of 40 V maximum for the FODM2705. |
