TMP112AIDRLR from UMW, in a SOT-563. 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	SCL	input	I²C/SMBus serial clock input. Open-drain, requires an external pull-up resistor. Absolute max voltage 6V.
2	GND	power_in	Ground reference for the device.
3	ALERT	output	Over-temperature alert output (SMBus Alert). Open-drain, requires an external pull-up resistor. Max voltage (V+)+0.3 and ≤5.5V.
4	ADD0	input	I²C slave address select. Tie to V+, GND, SCL, or SDA to select one of four addresses (allows up to four TMP112A on one bus).
5	V+	power_in	Positive supply input, 1.4V to 5.5V (3.3V nominal). Absolute max 6V. Bypass with a 0.1µF ceramic capacitor to GND.
6	SDA	bidirectional	I²C/SMBus serial data. Open-drain, requires an external pull-up resistor. Absolute max voltage 6V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tmp112aidrlr.step`	448 KB	You want the bare part, or you mark your own boards.
`tmp112aidrlr-etched.step`	1.9 MB	You want the part with `TMP112AIDRLR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 433 faces against 54 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.
