AS431ANTR-G1

Diodes Incorporated · Voltage Reference · SOT-23

AS431ANTR-G1 from Diodes Incorporated, in a SOT-23. 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 / feedback input. Internal op-amp compares this pin against the 2.500V bandgap reference and drives the internal shunt transistor. Typical reference input current IREF = 0.7µA (max 4µA). Absolute maximum input current 10mA.
2 CATHODE passive Cathode (K) of the shunt regulator. Sinks the regulation current when VREF pin reaches 2.500V. Operating cathode voltage range VREF to 36V, cathode current IKA 1mA to 100mA; absolute max VKA = 40V and IKA = 150mA. Off-state leakage 0.05µA typ at VKA = 36V.
3 ANODE passive Anode (A) of the shunt regulator. Common return terminal for the internal reference, op-amp and shunt transistor; typically connected to circuit ground in shunt-regulator use.

CAD (KiCad official)

  • Symbol: AS431ANTR-G1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: as431antr-g1-etched.step / as431antr-g1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); as431antr-g1.step / as431antr-g1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
as431antr-g1.step 59 KB You want the bare part, or you mark your own boards.
as431antr-g1-etched.step 1.8 MB You want the part with AS431ANTR-G1 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.
