AS431ANTR-TP

TECH PUBLIC · Voltage Reference · SOT-23

AS431ANTR-TP from TECH PUBLIC, 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. Compared internally to the 2.5V bandgap; the shunt regulator sinks cathode current when this pin exceeds Vref. Typical reference input current 0.7 uA (max 4 uA), max reference input current rating 10 mA.
2 CATHODE power_in Cathode (K). Shunt regulator output; sinks current from the load through an external series resistor to set the regulated node voltage. Continuous cathode current range 1 mA to 100 mA (absolute max -100 to +150 mA), Vka max 36 V.
3 ANODE power_in Anode (A). Reference/ground return for the shunt regulator; all voltages in the datasheet are referenced to this pin.

CAD (KiCad official)

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

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TECH PUBLIC datasheet (5 pp, sha256 515baa2b0164b8b1, retrieved 2026-08-17, tier: lcsc)
  • 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).
