Product details

AEC-Q100 shunt reference for under-hood regulation

It delivers a ±0.5% initial tolerance reference voltage adjustable from 1.24 V to 6 V, with a 15 mA output current capability and a 100 µA minimum cathode current for biasing.

125°C operating range and SOT-23-3 footprint

The SOT-23-3 package (TO-236-3 / SC-59 compatible) keeps the board footprint small and matches the standard TL431 pinout for drop-in upgrades.

No official successor or second-source cross-reference is published, but the standard TL431BQ pin-compatible family is widely available for dual-sourcing qualification.

Frequently asked questions

What is the equivalent of TLV431BQDBZRQ1?

The standard TL431BQ (non-automotive grade) shares the same SOT-23-3 pinout and adjustable 1.24 V to 6 V output, but lacks AEC-Q100 qualification.
