TS3431ILT

STMicroelectronics · Voltage References · SOT-23-3L

TS3431ILT from STMicroelectronics, in a SOT-23-3L. 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 Cathode passive Cathode of the shunt regulator, which sinks 0.5 to 100 mA operating current at 1.24 to 24 V cathode voltage (25 V absolute maximum cathode to anode).
2 Reference input Reference input of the shunt regulator, connected to the external resistor bridge that sets the output voltage between 1.24 V and 24 V, with reference input current absolute maximum range of 0.05 to +10 mA.
3 Anode passive Anode of the shunt regulator, normally connected to ground, with reverse breakdown current range of -100 to +150 mA.

CAD (KiCad official)

  • Symbol: TS3431ILT
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: ts3431ilt-etched.step / ts3431ilt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts3431ilt.step / ts3431ilt.glb are the bare package body.

Provenance

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