TC1047AVNBTR from Microchip Tech, 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	VDD	power_in	Input supply voltage. 2.5V to 5.5V for TC1047A (2.7V to 4.4V for TC1047). Absolute maximum +7V; typical supply current 35 µA.
2	VOUT	output	Temperature sensor analog output. Linear voltage output with 10 mV/°C slope; 500 mV at 0°C (100 mV at -40°C, 750 mV at 25°C, 1750 mV at 125°C). Source/sink capability 100 µA.
3	VSS	power_in	Ground reference terminal (0V).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tc1047avnbtr.step`	59 KB	You want the bare part, or you mark your own boards.
`tc1047avnbtr-etched.step`	1.6 MB	You want the part with `TC1047AVNBTR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 420 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.
