TMP175AIDR from UMW, in a SOP-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 I²C/SMBus interface. Open-drain output; requires an external pull-up resistor to V+.
2	SCL	input	Serial clock line for I²C/SMBus interface. Open-drain; requires an external pull-up resistor to V+. Fast mode up to 400 kHz, High-speed mode up to 2.75 MHz.
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	GND	power_in	Ground reference for the device.
5	A2	input	I²C address select bit 2. Connect to GND, V+, or leave floating (floating available on TMP175 only) to program the device address.
6	A1	input	I²C address select bit 1. Connect to GND, V+, or leave floating (floating available on TMP175 only) to program the device address.
7	A0	input	I²C address select bit 0. Connect to GND, V+, or leave floating (floating available on TMP175 only) to program the device address.
8	V+	power_in	Positive supply voltage input. Operating range 1.4V to 5.5V (nominal 3.3V); absolute maximum 6V.

TMP175AIDR

CAD (KiCad official)

Symbol: TMP175AIDR
Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOP-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tmp175aidr.step`	122 KB	You want the bare part, or you mark your own boards.
`tmp175aidr-etched.step`	1.6 MB	You want the part with `TMP175AIDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 439 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.
