Product details

Automotive-grade shunt reference with tighter tolerance

It delivers a ±0.5% reference tolerance — tighter than the standard 1% grade — which matters when setting a precise 1.24 V threshold for a comparator or biasing a sensor bridge in an ECU. Output is adjustable from 1.24 V up to 6 V via two external resistors, with a maximum cathode current of 15 mA. The shunt topology means it sinks current through an external series resistor; the minimum cathode current of 100 µA must be maintained to keep the reference in regulation.

Thermal range and package fit

The SOT-23-5 package (SC-74A, SOT-753) is a standard surface-mount footprint — no surprises for the pick-and-place line.

Listed as Active — no end-of-life or last-time-buy risk.

Frequently asked questions

Is TLV431BQDBVRQ1 automotive qualified?

Yes, it is listed under the Automotive, AEC-Q100 series, making it suitable for automotive-grade designs requiring the AEC-Q100 qualification.

What is the tolerance of TLV431BQDBVRQ1?

The reference tolerance is ±0.5%, tighter than the standard 1% grade available in the TLV431 family.

Can TLV431BQDBVRQ1 replace TL431?

The TLV431 is a lower-voltage variant of the TL431 — it operates down to 1.24 V reference vs the TL431's 2.5 V. Pin-compatible in many SOT-23 footprints, but the output range and cathode current differ; check the divider resistor values in your circuit before substituting.
