REF3430IDBVR

Texas Instruments · Voltage Reference · SOT-23-6

REF3430IDBVR from Texas Instruments, in a SOT-23-6. 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 GND_F power_in Ground force connection. Kelvin-sense ground return that carries the reference return current; tie to system ground at the load for best accuracy.
2 GND_S power_in Ground sense connection. High-impedance Kelvin sense of the load-side ground used by the internal reference amplifier to null IR drops.
3 EN input Enable input. Drive high to enable the reference, low to shut down. Active-high CMOS logic input referenced to GND.
4 IN power_in Input supply voltage connection. Accepts up to 12 V (recommended operating range). Bypass with a 1 µF CIN capacitor per the typical application.
5 OUT_S input Reference voltage output sense connection. High-impedance Kelvin sense of the load-side output used by the internal amplifier to null trace/pad IR drops. Datasheet lists this pin's TYPE as Input.
6 OUT_F output Reference voltage output force connection. Sources/sinks up to ±10 mA of load current at the 3.0 V reference voltage (REF3430). Bypass with a 10 µF COUT capacitor per the typical application.

Two STEP files. Same geometry, different body top:

File Size Use it when
ref3430idbvr.step 97 KB You want the bare part, or you mark your own boards.
ref3430idbvr-etched.step 2.3 MB You want the part with REF3430IDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 570 faces against 117 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: Texas Instruments datasheet (32 pp, sha256 4daf8dbbd5b7be4c, retrieved 2026-08-17, tier: manufacturer)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
