SLSS49E-3 from Slkor SLKORMICRO Elec, in a SOT-23. 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	Positive supply voltage input. Operating range 3 to 12 Vdc (absolute max 15 V, reverse -0.5 V). Typical supply current 5 mA at 5 Vdc.
2	GND	power_in	Ground return for the Hall element, bias, and output stage.
3	Vout	output	Ratiometric analog output proportional to the applied magnetic field. Quiescent output ~2.5 V (B=0) at VDD=5 V; ~1 V at -460 G, ~4 V at +460 G. Sensitivity ~3.25 mV/G at 5 V; output current up to 1.5 mA; recommended load ≥200 kΩ for

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`slss49e-3.step`	59 KB	You want the bare part, or you mark your own boards.
`slss49e-3-etched.step`	1.8 MB	You want the part with `SLSS49E-3` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 423 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.
