AZ431BN-TP

TECH PUBLIC · Voltage Reference · SOT-23

AZ431BN-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 (feedback) input. Internally compared against the 2.500 V bandgap; drives the output transistor to hold this pin at Vref. Typical reference input current 0.7 uA (max 4.0 uA); max ±10 mA absolute.
2 CATHODE passive Cathode (K) of the shunt regulator. Sinks the regulation current from the load through an external bias resistor. Operating cathode current 1.0 mA to 100 mA (abs max -100 to +150 mA); Vka up to 36 V; dynamic impedance ~0.15 Ω typ.
3 ANODE passive Anode (A) of the shunt regulator; reference node for Vka and Vref. Typically tied to circuit ground/return.

Ordering variants

  • AZ431BN-TP

CAD (KiCad official)

  • Symbol: AZ431BN-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: az431bn-tp-etched.step / az431bn-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az431bn-tp.step / az431bn-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 af258e73aec7d5cb, 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).
