AZ431LAKTR-TP

TECH PUBLIC · Voltage Reference · SOT-23-5

AZ431LAKTR-TP from TECH PUBLIC, in a SOT-23-5. 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 NC unconnected Pin 1 is attached to the substrate and must be connected to ANODE or left open.
2 NC unconnected Pin 2 is attached to the substrate and must be connected to ANODE or left open.
3 CATHODE passive Cathode of the shunt regulator, rated 18 V maximum cathode voltage (VKA) with continuous cathode current of 0.1 mA to 100 mA.
4 REF input Reference input that sets the output voltage via an external divider around VREF of 1.24 V (1.234 V to 1.246 V), with maximum reference input current of 10 mA.
5 ANODE power_in Anode of the shunt regulator, the reference for all voltage values, normally connected to ground.

CAD (KiCad official)

  • Symbol: AZ431LAKTR-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: az431laktr-tp-etched.step / az431laktr-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az431laktr-tp.step / az431laktr-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 a74e1b28c2eb9cb7, retrieved 2026-11-05, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
