sc2242so-tr.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 -> 3 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

SC2242SO-TR

Semiment SC2242SO · Hall Sensor · SOT-23

SC2242SO-TR from Semiment SC2242SO, in a SOT-23. 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 VDD power_in Supply voltage input, 2.5 V to 24 V operating range (absolute maximum -28 V to +28 V). A decoupling capacitor to GND is recommended (C1 in the functional block diagram).
2 OUT output Open-drain Hall latch output with internal 10 kΩ pull-up to VDD. Sinks up to 20 mA when active (absolute max 30 mA). Output goes low when magnetic field exceeds BOP (+2 mT typ) and returns high when it falls below BRP (-2 mT typ).
3 GND power_in Ground reference for the device.

CAD (KiCad official)

  • Symbol: SC2242SO-TR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sc2242so-tr-etched.step / sc2242so-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sc2242so-tr.step / sc2242so-tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sc2242so-tr.step 59 KB You want the bare part, or you mark your own boards.
sc2242so-tr-etched.step 2.0 MB You want the part with SC2242SO-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 475 faces against 69 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.
