HX6286UA from HUAXIN, in a TO-92S. 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 input. Operating range 2.5V to 24V (absolute max -28V to +28V, with reverse-polarity protection on this pin). Bypass with 10nF ceramic to GND close to the pin.
2	GND	power_in	Ground / return reference for the supply and the open-collector output.
3	Output	output	Open-collector digital output. Pulls low (Vsat ≤ 400 mV @ 20 mA) when the sensed S-pole field exceeds BOP (typ 60 G / max 100 G); releases (leakage ≤ 10 µA @ 20V) when the field falls below BRP (typ 40 G / max 80 G). Requires an external pull-up (e.g. R1 = 1 kΩ) to VDD; 1 nF cap to GND recommended. Sinks up to 50 mA; rated 0.5V-24V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hx6286ua.step`	27 KB	You want the bare part, or you mark your own boards.
`hx6286ua-etched.step`	1.5 MB	You want the part with `HX6286UA` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 368 faces against 19 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.
