MT6133AT from Magn Tek, 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	Power supply input. Operating range 1.65 V to 5.0 V (absolute max 7 V). Typical bypass: 100 nF between VCC and GND.
2	OUT	output	Open-drain digital output on MT6133. Pulls low when
3	GND	power_in	Ground reference.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mt6133at.step`	59 KB	You want the bare part, or you mark your own boards.
`mt6133at-etched.step`	1.4 MB	You want the part with `MT6133AT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 350 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.
