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 -> 0 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

SC2242UA-BK-Q

Semiment SC2242UA · Hall Sensor · TO-92S

SC2242UA-BK-Q from Semiment SC2242UA, in a TO-92S. 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 2.5 V to 24 V supply input. Absolute maximum ±28 V; reverse-supply protected to -28 V. Recommend a 0.1 µF bypass (C1) close to the pin, and an optional 100 Ω series resistor (R1) for unregulated supplies.
2 GND power_in Ground reference for the device. (TO-92S 'UA' package: pin 2 is GND; SOT-23-3L 'SO' package places GND on pin 3.)
3 OUT output Open-drain latched Hall output with an internal 10 kΩ pull-up to VDD. Drives LOW (turn-on) when the south-pole B-field exceeds B_OP (typ. +2.0 mT); releases HIGH when B falls below B_RP (typ. -2.0 mT). Sinks up to 20 mA; V_OUT absolute max 28 V with a 1 kΩ pull-up.

CAD (KiCad official)

  • Symbol: SC2242UA-BK-Q
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: sc2242ua-bk-q-etched.step / sc2242ua-bk-q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sc2242ua-bk-q.step / sc2242ua-bk-q.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sc2242ua-bk-q.step 27 KB You want the bare part, or you mark your own boards.
sc2242ua-bk-q-etched.step 2.0 MB You want the part with SC2242UA-BK-Q already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 507 faces against 19 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.
