ZRB500F03TA

Diodes Incorporated · Voltage References · SOT-23

ZRB500F03TA 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 on the SOT23 package.
2 GND power_in Pin 2 is the ground reference for the reference voltage, and all voltages in the absolute maximum ratings are referenced to GND.
3 VR output Pin 3 is the 5.0 V precision voltage reference output, operating over a recommended reverse current of 0.05 mA to 15 mA.

CAD (KiCad official)

  • Symbol: ZRB500F03TA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: zrb500f03ta-etched.step / zrb500f03ta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); zrb500f03ta.step / zrb500f03ta.glb are the bare package body.
