ZR40402F50TA

Diodes Incorporated · Voltage References · SOT-23

ZR40402F50TA 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 is left floating or connected to pin 2 (GND), per the datasheet's pin assignment note.
2 GND power_in Ground reference pin (Gnd) of the 5.0 V shunt reference; reverse current is specified from 60µA to 15mA recommended, 25mA absolute maximum.
3 VR passive Reference voltage pin (VR) of 5.0 V nominal (4.95 to 5.05 V at IR = 150µA, 1% tolerance); reverse current 25 mA absolute maximum.
