TMP175AIDR

UMW · Temperature and Humidity Sensor · SOP-8

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.

Ordering variants

Same part, different packaging or reel option.

  • 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 files: tmp175aidr-etched.step / tmp175aidr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmp175aidr.step / tmp175aidr.glb are the bare package body.

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: UMW datasheet (22 pp, sha256 7d26273fe4ee8a02, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
