TS431BIYLT

STMicroelectronics · Voltage Reference · SOT-23-5

TS431BIYLT from STMicroelectronics, 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 No internal connection on this pin.
2 NC* unconnected Do not connect this pin, or connect it to Anode.
3 Cathode passive Cathode of the shunt regulator; operating cathode current is 0.06 to 30 mA, VKA is 1.24 to 6 V in operation, and the absolute maximum VKA is 10 V.
4 Reference input Reference input that sets the output voltage via an external resistor divider, with Vref of 1.24 V typ. and absolute maximum input current of -0.05 to +3 mA.
5 Anode passive Anode of the shunt regulator, normally connected to ground.

CAD (KiCad official)

  • Symbol: TS431BIYLT
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ts431biylt-etched.step / ts431biylt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts431biylt.step / ts431biylt.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (16 pp, sha256 ec56fdab04a9692d, retrieved 2026-11-05, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+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).
