AH49ENTR-G1 from Diodes Incorporated, 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	VCC	power_in	Supply voltage input, typically 5V. Powers the Hall sensor, amplifier, and output current source (typical supply current 3.5mA).
2	OUT	output	Analog linear output. Sources current (65uA typical internal source) and produces a voltage proportional to the applied magnetic field, biased around VCC/2 with polarity indicating field direction.
3	GND	power_in	Ground reference pin for the device.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ah49entr-g1.step`	59 KB	You want the bare part, or you mark your own boards.
`ah49entr-g1-etched.step`	1.5 MB	You want the part with `AH49ENTR-G1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 396 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.
