TP431C249S3

TECH PUBLIC · Voltage Reference · SOT-23

TP431C249S3 from TECH PUBLIC, in a SOT-23. 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 adjustable shunt reference; continuous cathode current 1.0 mA min to 100 mA max, cathode voltage up to 36 V (VKA absolute maximum).
2 REF input Reference input that sets the output voltage via an external divider, with VREF of 2.495 V typ and reference input current rated up to 10 mA absolute maximum.
3 ANODE passive Anode of the shunt reference, normally connected to ground, and the point to which all voltage ratings are referenced.
