tl432bidbzr.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

TL432BIDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TL432BIDBZR from Texas Instruments, in a SOT-23-3. 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 REF input Reference / threshold input. Internal error amplifier compares this pin against the internal 2.5 V bandgap; the resistor divider from CATHODE to ANODE ties here to program the regulated Vka. Reference input current range -0.05 to 10 mA (absolute max).
2 CATHODE passive Shunt cathode (K) - the regulated node. Sinks 1 mA to 100 mA when Vref threshold is exceeded. Vka range Vref to 36 V (abs max 37 V); continuous cathode current -100 to 150 mA.
3 ANODE passive Shunt anode (A), the common/ground return. All voltage specifications are referenced to this pin.

CAD (KiCad official)

  • Symbol: TL432BIDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tl432bidbzr-etched.step / tl432bidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl432bidbzr.step / tl432bidbzr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tl432bidbzr.step 59 KB You want the bare part, or you mark your own boards.
tl432bidbzr-etched.step 1.8 MB You want the part with TL432BIDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 457 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:
