TMP112BIDRLR 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	Serial clock input for the SMBus/I²C interface. Open-drain, requires an external pull-up resistor. Supports fast mode up to 400 kHz and high-speed mode up to 2.75 MHz.
2	GND	power_in	Ground reference for the device. Connect to the system ground plane.
3	ALERT	output	Over-temperature alert output. Open-drain, requires an external pull-up resistor. Voltage limited to (V+)+0.3V and ≤5.5V absolute maximum.
4	ADD0	input	Address select input. Tie to V+, GND, SCL, or SDA to select one of four possible I²C slave addresses, allowing up to four devices on one bus.
5	V+	power_in	Positive supply voltage input, 1.4V to 5.5V (3.3V nominal). Absolute maximum 6V. Bypass with a 0.1µF ceramic capacitor to GND close to the device.
6	SDA	bidirectional	Serial data line for the SMBus/I²C interface. Open-drain, requires an external pull-up resistor. Used for both data input and output.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tmp112bidrlr.step`	448 KB	You want the bare part, or you mark your own boards.
`tmp112bidrlr-etched.step`	2.0 MB	You want the part with `TMP112BIDRLR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 462 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.
