SS39ET from Honeywell, 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	Positive supply voltage (Vs). Operating range 2.7 Vdc to 6.5 Vdc; absolute maximum -5.0 Vdc to 8.0 Vdc. Typical supply current 6 mA at 5 Vdc.
2	OUTPUT	output	Linear current-sourcing analog output. Voltage varies proportionally with magnetic field: null 2.5 Vdc at 0 Gauss, sensitivity typ. 1.4 mV/Gauss, output span 0.95 V to (Vs - 0.95) V, max output current 1.5 mA. Response time typ. 3 μs.
3	GND	power_in	Ground / negative supply return (V-).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ss39et.step`	59 KB	You want the bare part, or you mark your own boards.
`ss39et-etched.step`	1.4 MB	You want the part with `SS39ET` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 337 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.
