ZR40402F25TA

Diodes Incorporated · Voltage Reference · SOT-23

ZR40402F25TA 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 NC/VR passive No internal connection; may be left floating or tied to pin 2 (VR) on the SOT23-F package.
2 Gnd passive Ground / anode of the shunt reference. Return path for reverse current IR (60µA to 15mA recommended).
3 VR passive Reverse breakdown / reference output pin (cathode of shunt reference). Regulates to 2.5V nominal (±2% for the F25TA suffix) when biased with 60µA-15mA of reverse current through an external series resistor.
