tpv321s5.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

TPV321S5

TECH PUBLIC · Operational Amplifier · SOT-23-5

TPV321S5 from TECH PUBLIC, 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 +IN input Non-inverting analog input of the op-amp. Common-mode range extends from Vss-0.1V to VDD+0.1V (rail-to-rail input).
2 -Vs power_in Negative supply rail (Vss / GND in single-supply operation). Supply range 2.2V to 5.5V referenced to +Vs; absolute max -0.5V to +7V vs +Vs.
3 -IN input Inverting analog input of the op-amp. Common-mode range extends from Vss-0.1V to VDD+0.1V (rail-to-rail input).
4 OUT output Rail-to-rail op-amp output. Swings to within ~6mV of either supply rail with a 100kΩ load; short-circuit current ±20mA typical.
5 +Vs power_in Positive supply rail (VDD). Single-supply operation 2.2V to 5.5V; absolute maximum 7V above -Vs.

Ordering variants

Same part, different packaging or reel option.

  • TPV321S5
  • TPV321S5S8
  • TPV321S5M8

CAD (KiCad official)

  • Symbol: TPV321S5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tpv321s5-etched.step / tpv321s5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpv321s5.step / tpv321s5.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tpv321s5.step 85 KB You want the bare part, or you mark your own boards.
tpv321s5-etched.step 1.6 MB You want the part with TPV321S5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 395 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.
