SC2402SO-N-TR from Semiment SC2402SO N, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	VDD	power_in	Supply voltage input, 2.5 V to 18 V operating range (absolute max 20 V).
2	OUT	output	Open-drain digital Hall-effect output. Sinks up to 30 mA; typical RDS(on) 20 Ω at 25 °C. Requires an external pull-up resistor.
3	GND	power_in	Ground reference for the device.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sc2402so-n-tr.step`	59 KB	You want the bare part, or you mark your own boards.
`sc2402so-n-tr-etched.step`	2.1 MB	You want the part with `SC2402SO-N-TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 513 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
