FODM2705R2

onsemi · Transistor, Photovoltaic Output Optoisolators · SOP-4-2.54mm

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.
