TL432BIDBZT

Texas Instruments · Voltage Reference · SOT-23-3

TL432BIDBZT from Texas Instruments, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Voltage reference input that sets the regulation threshold; draws Iref = 2 µA typ / 4 µA max at IKA = 10 mA and must not be left open because the internal NPN base requires IREF ≥ 4 µA to remain in its operating region.
2 CATHODE bidirectional Shunt regulator cathode (I/O); operating range VKA = Vref to 36 V, continuous IKA = 1 mA to 100 mA, dynamic output impedance
3 ANODE power_in Common anode, typically connected to circuit ground; serves as the current return path for up to 100 mA continuous cathode current.

CAD (KiCad official)

  • Symbol: TL432BIDBZT
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tl432bidbzt-etched.step / tl432bidbzt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tl432bidbzt.step / tl432bidbzt.glb are the bare package body.
