ZR431F005TA

Diodes Incorporated · Voltage Reference · SOT-23

ZR431F005TA from Diodes Incorporated, 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 VREF input Reference input. Compared internally against the 2.5 V bandgap reference; drive from the R1/R2 divider between Vz and GND to program the shunt voltage (VOUT = (1 + R1/R2) * VREF).
2 Vz power_in Cathode (regulated) terminal. Sinks the shunt current from the external series resistor; regulates the node to the programmed voltage. Absolute max 20 V / 150 mA; minimum cathode current for regulation ~50 uA typ.
3 GND power_in Anode / ground return terminal. All device voltages are referenced to this pin.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (11 pp, sha256 93e5c58d4c91bc6c, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
