ZR431FTA-TP

TECH PUBLIC · Voltage Reference · SOT-23

ZR431FTA-TP 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 REF input Reference input that sets the output voltage via an external R1/R2 divider, with Vref of 2.500V typ (2.488V min, 2.512V max) and reference input current of 0.7uA typ, 4.0uA max.
2 CATHODE passive Cathode of the adjustable shunt regulator, rated 36V maximum cathode voltage, with continuous cathode current of 1.0mA min to 100mA operating (-100 to +150mA absolute maximum).
3 ANODE power_in Anode of the shunt regulator, normally connected to ground, and the reference for all voltage ratings.
