ZRC250F03TA

Diodes Incorporated · Voltage References · SOT-23

ZRC250F03TA 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 floating or connected to pin 2 according to the datasheet, and no other function is stated for it.
2 GND power_in Ground reference for the device; all absolute maximum voltages are specified relative to GND.
3 VR passive Voltage reference terminal with reverse breakdown voltage of 2.5 V (2.475 V to 2.525 V at IR = 150 µA) and recommended operating current of 0.02 mA to 5 mA.
