SS341RT from Honeywell, 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	VCC	power_in	Supply voltage input (Vs+). Operating range 3 Vdc to 24 Vdc (12 Vdc max at 150 °C). Absolute maximum ±28 V; built-in reverse polarity protection.
2	OUTPUT	output	Open-collector (current-sinking) digital output. Vsat ≤ 0.4 Vdc at 20 mA when magnetic flux > Bop; leakage ≤ 10 µA off. Rise/fall time ≤ 1.5 µs. Applied output voltage max 28 V, current max 20 mA. Requires external pull-up.
3	GND	power_in	Ground reference (-).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ss341rt.step`	59 KB	You want the bare part, or you mark your own boards.
`ss341rt-etched.step`	1.5 MB	You want the part with `SS341RT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 362 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.
