H8116A30NR from Shanghai Siproin Microelectronics, 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	power_out	Regulated boost output voltage pin (3.0V typ for the '30' suffix; internally settable range 2.1V-5.5V). Connect the output filter capacitor from this pin to VSS. Absolute max VSS-0.3V to VSS+8V.
2	VSS	power_in	Ground (0V) reference pin for the converter. All external capacitors and the input return connect here.
3	LX	power_out	Switching node / external inductor connection pin. The internal power MOSFET switches this node between VSS and VOUT; the inductor is tied from the input supply to LX. Rated 1000 mA peak; absolute max voltage VSS-0.3V to VSS+8V. Internal protection turns the MOSFET off if LX exceeds the limit.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`h8116a30nr.step`	59 KB	You want the bare part, or you mark your own boards.
`h8116a30nr-etched.step`	1.9 MB	You want the part with `H8116A30NR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 461 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.
