FODM452 from onsemi, in a SOIC-5. 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-side pin, shorted with pin 3 for the two-terminal isolation test (forward current 16 mA typical test condition, 25 mA max average). |
| 3 | CATHODE | passive | LED cathode; input-side pin, shorted with pin 1 for the two-terminal isolation test. |
| 4 | GND | power_in | Output ground reference for the detector side. |
| 5 | VO | output | Open-collector detector output that is high when the LED is off and low when on; rated -0.5 to 20 V. |
| 6 | VCC | power_in | Output supply voltage for the detector, rated -0.5 to 30 V. |
