XC61CN2702MR-G from Torex Semicon, 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	VOUT	output	N-channel open-drain detector output. Pulled low when VDD drops below the 2.7 V detect threshold; high-impedance (requires external pull-up) when VDD is above the release voltage.
2	VSS	power_in	Ground / negative supply reference.
3	NC	unconnected	No internal connection. Leave floating or tie to VSS.
4	NC	unconnected	No internal connection. Leave floating or tie to VSS.
5	VDD	power_in	Positive supply and monitored rail input. Operating range typically 1.0 V to 10 V; the detector compares this rail against the internal 2.7 V threshold.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`xc61cn2702mr-g.step`	59 KB	You want the bare part, or you mark your own boards.
`xc61cn2702mr-g-etched.step`	2.2 MB	You want the part with `XC61CN2702MR-G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 546 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.
