TLA431AIDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TLA431AIDBZR 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 CATHODE bidirectional Shunt current/voltage input (cathode); operates from VREF up to 36V (37V absolute max) with 0.2mA to 100mA continuous cathode current.
2 REF input Reference input that sets the threshold relative to the common anode; absolute maximum reference input current is -0.05mA to 10mA.
3 ANODE power_in Common pin, normally connected to ground.

CAD (KiCad official)

  • Symbol: TLA431AIDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: tla431aidbzr-etched.step / tla431aidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tla431aidbzr.step / tla431aidbzr.glb are the bare package body.
