tmp112aidrlr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 6 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TMP112AIDRLR

UMW · Temperature and Humidity Sensor · SOT-563

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.

Same part, different packaging or reel option.

  • TMP112AIDRLR

CAD (KiCad official)

  • Symbol: TMP112AIDRLR
  • Footprint: Package_TO_SOT_SMD:SOT-563
  • 3D model: SOT-563 (KiCad packages3D, STEP)
  • 3D model files: tmp112aidrlr-etched.step / tmp112aidrlr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmp112aidrlr.step / tmp112aidrlr.glb are the bare package body.

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.

Provenance

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

  • Datasheet: UMW datasheet (24 pp, sha256 62c8953a9c6be1ea, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
