ZXRE125FFTA

Diodes Incorporated · Voltage References · SOT-23

ZXRE125FFTA from Diodes Incorporated, 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 NC unconnected Pin 1 may be left floating or connected to pin 2 (Gnd), per the SOT23 pin assignment note.
2 Gnd power_in Ground (anode) of the reference; pin 1 may be connected to it, and it is the reference for the 1.22V reverse breakdown voltage.
3 VR passive Reference voltage terminal (cathode) giving 1.22V nominal (3% tolerance for grade F) at recommended operating current of 0.008 to 20mA.
