tpas179-92lf.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 -> 6 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

TPAS179-92LF

TECH PUBLIC · Analog Switches, Multiplexers · SOT-363

TPAS179-92LF from TECH PUBLIC, in a SOT-363. 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 RF2 passive RF port 2. DC-3 GHz RF I/O connected to RFC when VC2=High/VC1=Low (insertion loss ~0.4 dB @ 2.5 GHz). Requires a series DC blocking capacitor C1 (56 pF for >500 MHz operation).
2 GND power_in Ground reference for the RF switch. Connect to system ground with a low-inductance path.
3 RF1 passive RF port 1. DC-3 GHz RF I/O connected to RFC when VC1=High/VC2=Low (insertion loss ~0.4 dB @ 2.5 GHz). Requires a series DC blocking capacitor C1 (56 pF for >500 MHz operation).
4 VC1 input Switch control input 1. Logic High (2.8 V to 5 V) selects the RFC-RF1 path (insertion loss); Logic Low (-0.2 V to 0.2 V) isolates RF1. Abs max -6.0 to +6.0 V;
5 RFC passive RF common port. Routed to RF1 or RF2 per VC1/VC2 truth table. DC-3 GHz operation with VSWR ~1.2 and IIP3 ~55 dBm. Requires a series DC blocking capacitor C1 (56 pF for >500 MHz operation).
6 VC2 input Switch control input 2. Logic High (2.8 V to 5 V) selects the RFC-RF2 path (insertion loss); Logic Low (-0.2 V to 0.2 V) isolates RF2. Abs max -6.0 to +6.0 V;

  • TPAS179-92LF

CAD (KiCad official)

  • Symbol: TPAS179-92LF
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: tpas179-92lf-etched.step / tpas179-92lf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpas179-92lf.step / tpas179-92lf.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tpas179-92lf.step 99 KB You want the bare part, or you mark your own boards.
tpas179-92lf-etched.step 1.9 MB You want the part with TPAS179-92LF already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 489 faces against 117 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.
