tp8541artz.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

TP8541ARTZ

TECH PUBLIC · Operational Amplifier · SOT-23-5

TP8541ARTZ 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	OUT	output	Amplifier output. Rail-to-rail output swing; typical VOL-VSS / VDD-VOH of 6mV with RL=100kΩ.
2	VSS	power_in	Negative supply / ground reference. Typically tied to 0V for single-supply operation (VDD 1.8V to 5.5V above VSS).
3	IN+	input	Non-inverting analog input. Rail-to-rail common-mode range from VSS-0.1V to VDD+0.1V; input bias current ~10pA typ.
4	IN-	input	Inverting analog input. Rail-to-rail common-mode range from VSS-0.1V to VDD+0.1V; input bias current ~10pA typ.
5	VDD	power_in	Positive supply. Operating range 1.8V to 5.5V, absolute max 7V (VDD-VSS). Quiescent current 55µA typ per amplifier.

TP8541ARTZ

CAD (KiCad official)

Symbol: TP8541ARTZ
Footprint: Package_TO_SOT_SMD:SOT-23-5
3D model: SOT-23-5 (KiCad packages3D, STEP)
3D model files: tp8541artz-etched.step / tp8541artz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tp8541artz.step / tp8541artz.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tp8541artz.step`	85 KB	You want the bare part, or you mark your own boards.
`tp8541artz-etched.step`	1.7 MB	You want the part with `TP8541ARTZ` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 435 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.
