TMP175AIDGKR from UMW, in a MSOP-8. 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	SDA	bidirectional	Serial data line for the SMBus / I2C interface. Open-drain; requires an external pull-up resistor to V+.
2	SCL	input	Serial clock input for the SMBus / I2C interface. Open-drain; requires an external pull-up resistor to V+. Supports fast mode up to 400 kHz and high-speed mode up to 2.75 MHz.
3	ALERT	output	Over-temperature alert output. Open-drain; requires an external pull-up resistor. Asserts when the measured temperature crosses the programmed T_HIGH / T_LOW thresholds.
4	GND	power_in	Ground return for the device. Connect to system ground.
5	A2	input	I2C slave address select bit A2. Tie to GND, V+, or leave floating (float option available only on TMP175) to set one of the device address bits.
6	A1	input	I2C slave address select bit A1. Tie to GND, V+, or leave floating (float option available only on TMP175) to set one of the device address bits.
7	A0	input	I2C slave address select bit A0. Tie to GND, V+, or leave floating (float option available only on TMP175) to set one of the device address bits.
8	V+	power_in	Positive supply voltage input, 1.4 V to 5.5 V (absolute maximum 6 V). Bypass to GND with a 0.1 µF ceramic capacitor placed close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tmp175aidgkr.step`	123 KB	You want the bare part, or you mark your own boards.
`tmp175aidgkr-etched.step`	2.0 MB	You want the part with `TMP175AIDGKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 513 faces against 147 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.
