TL432BQDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TL432BQDBZR 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 relative to the common ANODE. Compared internally to the 2.495 V bandgap reference; when V(REF) exceeds Vref, cathode current begins to sink. Ireference input current is typically 2 µA (max 4 µA).
2 CATHODE passive Shunt current/voltage input (K). Sinks the shunt current (Imin ≈ 0.4 mA up to 100 mA operating, 150 mA abs max) when the REF threshold is exceeded. Cathode voltage operates from Vref up to 36 V (37 V abs max).
3 ANODE passive Common pin (A), normally connected to circuit ground. All device parameters are referenced to ANODE unless otherwise noted.

CAD (KiCad official)

  • Symbol: TL432BQDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tl432bqdbzr-etched.step / tl432bqdbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl432bqdbzr.step / tl432bqdbzr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tl432bqdbzr.step 59 KB You want the bare part, or you mark your own boards.
tl432bqdbzr-etched.step 1.9 MB You want the part with TL432BQDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 476 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:

  • Datasheet: Texas Instruments datasheet (76 pp, sha256 5cf02342e69c1244, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
