Product details

Precision shunt reference in a small SC-70-6

The Texas Instruments TL431BIDCKR is a three-terminal adjustable shunt voltage reference with a ±0.5% initial tolerance, housed in a 6-pin SC-70-6 (SOT-363) package for surface-mount assembly.

Tolerance and temperature range for industrial designs

The ±0.5% tolerance (B-grade) is tighter than the standard TL431's ±1% or ±2%, making it a fit for precision power-supply feedback loops, data-converter references, and comparator thresholds where voltage accuracy drives system performance.

Output current and cathode current limits

The 100 mA output current rating defines the maximum load the shunt can regulate; the 700 µA minimum cathode current (Imin) sets the lower bias floor for stable operation — below this the reference may drop out of regulation.

Frequently asked questions

What is the tolerance of TL431BIDCKR?

The TL431BIDCKR has a ±0.5% initial tolerance, which is the tightest grade in the TL431B family.
