NL17SZ07DFT2G from onsemi, in a SOT-353. 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	NC	unconnected	No connect. Leave floating or tie to any logic level; not internally bonded on the SOT-353/SOT-553 variant matching the DFT2G suffix.
2	IN A	input	Logic input to the non-inverting buffer. Over-voltage tolerant: VI may be 0 to 7.0 V regardless of VCC (VCC 0.5-5.5 V). VIH >= 0.7VCC (2.3-5.5 V range); VIL <= 0.3VCC.
3	GND	power_in	Ground reference (0 V). DC ground current per pin absolute-max +/-100 mA.
4	OUT Y	output	Open-drain non-inverting buffer output. Follows IN A logically (H input -> high-Z; L input -> low). External pull-up resistor required; pull-up rail may be 0 to 7.0 V (over-voltage tolerant). Sinks up to 24 mA (VOL <= 0.55 V at IOL = 24 mA, VCC = 3.0 V).
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V data-retention only). Absolute max -0.5 to +7.0 V. Near-zero static supply current (1 uA typ at VCC = 5.5 V).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`nl17sz07dft2g.step`	87 KB	You want the bare part, or you mark your own boards.
`nl17sz07dft2g-etched.step`	1.9 MB	You want the part with `NL17SZ07DFT2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 492 faces against 102 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.
