TP432R124S3

TECH PUBLIC · Voltage Reference · SOT-23

TP432R124S3 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 1.24 V (typ) bandgap reference; the device sinks cathode current to regulate this pin to Vref. Reference input current is 0.7 µA typ (4 µA max); absolute max input current 10 mA.
2 CATHODE input Cathode (Vka). Shunt-regulator current-sink terminal; connects through a series resistor RB to the supply rail. Absolute maximum Vka = 18 V; continuous cathode current range 0.1 mA to 100 mA (abs max −100 to +150 mA). Dynamic impedance 0.05 Ω typ.
3 ANODE power_in Anode. Ground / return terminal for the shunt regulator; all voltages in the datasheet are referenced to this pin.

  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tp432r124s3-etched.step / tp432r124s3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tp432r124s3.step / tp432r124s3.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (5 pp, sha256 41280134c062bf39, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
