AZ431LANTR-E1

Diodes Incorporated · Voltage Reference · SOT-23

AZ431LANTR-E1 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 input to the internal error amplifier. Compared against the internal 1.240 V bandgap; regulation drives cathode current until VREF = 1.240 V. Reference input current ~0.15 uA typ (0.4 uA max).
2 ANODE power_in Anode terminal of the shunt regulator; the common/return node. Typically tied to circuit ground in shunt-regulator or programmable-zener configurations.
3 CATHODE power_in Cathode terminal; sinks the shunt/regulation current. Continuous cathode current range -100 to 100 mA (abs max), recommended 0.1 to 100 mA; max cathode voltage 20 V (abs), 18 V (recommended). When shorted to REF, acts as a 1.240 V precision reference.

CAD (KiCad official)

  • Symbol: AZ431LANTR-E1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: az431lantr-e1-etched.step / az431lantr-e1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az431lantr-e1.step / az431lantr-e1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
az431lantr-e1.step 59 KB You want the bare part, or you mark your own boards.
az431lantr-e1-etched.step 1.5 MB You want the part with AZ431LANTR-E1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 414 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.
