SC2448SO-TR-Q from Semiment, in a SOT-23-3. 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 | VDD | power_in | Supply pin for the sensor, with an operating supply voltage of 2.5 V to 24 V. |
| 2 | OUT | output | Open-drain output that requires an external pull-up resistor to a voltage that may differ from VDD. |
| 3 | GND | power_in | Ground pin. |
