ss39et.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

SS39ET

Honeywell · Hall Sensor · SOT-23

SS39ET from Honeywell, 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 VCC power_in Positive supply voltage (Vs). Operating range 2.7 Vdc to 6.5 Vdc; absolute maximum -5.0 Vdc to 8.0 Vdc. Typical supply current 6 mA at 5 Vdc.
2 OUTPUT output Linear current-sourcing analog output. Voltage varies proportionally with magnetic field: null 2.5 Vdc at 0 Gauss, sensitivity typ. 1.4 mV/Gauss, output span 0.95 V to (Vs - 0.95) V, max output current 1.5 mA. Response time typ. 3 μs.
3 GND power_in Ground / negative supply return (V-).

CAD (KiCad official)

  • Symbol: SS39ET
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ss39et-etched.step / ss39et-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ss39et.step / ss39et.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ss39et.step 59 KB You want the bare part, or you mark your own boards.
ss39et-etched.step 1.4 MB You want the part with SS39ET already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 337 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.

Provenance

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

  • Datasheet: Honeywell datasheet (9 pp, sha256 d0d7d6974a205ed9, 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).
