ZRC250F01TA

Diodes Incorporated · Voltage Reference · SOT-23

ZRC250F01TA 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/GND passive No internal connection. Per datasheet, pin 1 may be left floating or connected to pin 2 (GND).
2 GND passive Ground / anode of the shunt reference. Return terminal; reference voltage VR is measured from pin 3 to this pin.
3 VR passive Reverse breakdown / cathode terminal of the 2.5V shunt reference. Sink 20µA to 5mA (recommended) through this pin via an external series resistor to establish the 2.5V reference. Absolute max reverse current 25mA.

Two STEP files. Same geometry, different body top:

File Size Use it when
zrc250f01ta.step 59 KB You want the bare part, or you mark your own boards.
zrc250f01ta-etched.step 1.9 MB You want the part with ZRC250F01TA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 466 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Diodes Incorporated datasheet (5 pp, sha256 5054cff99b70e2df, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
