gs331-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 -> 5 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

GS331-TR

Gainsil · Comparators · SOT-23-5

GS331-TR from Gainsil, in a SOT-23-5. 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 INPUT- input Inverting comparator input. Input common-mode range includes ground; upper end is VCC-1.5V. Should not be driven more than 0.3V below ground. Typical input bias current 25nA.
2 GND power_in Ground / negative supply return. For single-supply operation tie to 0V; for split-supply operation connect to the negative rail (±1.0V to ±18V).
3 INPUT+ input Non-inverting comparator input. Input common-mode range includes ground; upper end is VCC-1.5V. Should not be driven more than 0.3V below ground. Typical input bias current 25nA.
4 OUTPUT output Open-collector comparator output. Requires an external pull-up resistor to VCC (or another rail up to 40V). Typical sink current 16mA; saturation voltage 200mV at 4mA sink; leakage 0.1nA typ.
5 VCC power_in Positive supply input. Single supply 2.0V to 36V or split supply +1.0V to +18V. Absolute maximum 40V (single) or ±20V (split). Typical supply current 0.4mA at 5V.

  • GS331-TR

CAD (KiCad official)

  • Symbol: GS331-TR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: gs331-tr-etched.step / gs331-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs331-tr.step / gs331-tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
gs331-tr.step 85 KB You want the bare part, or you mark your own boards.
gs331-tr-etched.step 1.7 MB You want the part with GS331-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 412 faces against 102 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:
