LMT84DCKR from Texas Instruments, in a SC-70-5. 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	GND	power_in	Power supply ground. Direct connection to the back side of the die.
2	GND	power_in	Power supply ground. Direct connection to the back side of the die.
3	OUT	output	Analog output voltage that is inversely proportional to temperature (approx. -5.5 mV/°C). Push-pull output with ±50-µA drive capability; short-circuit protected. Can drive up to 1100 pF load capacitance.
4	VDD	power_in	Positive supply voltage input. Operating range 1.5 V to 5.5 V; absolute max 6 V. Quiescent current typ. 5.4 µA.
5	GND	power_in	Power supply ground.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmt84dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`lmt84dckr-etched.step`	1.6 MB	You want the part with `LMT84DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 404 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.
