TL431AQDBZRG4

Overview

The TL431AQDBZRG4 is an automotive-grade adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495V to 36V and supports a maximum cathode current of 100mA. The device features an initial accuracy of 1% and a maximum temperature coefficient of 92ppm/°C. It is designed for operation between -40°C and +125°C, housed in a surface-mount SOT-23-3 package with tape and reel packaging.

Feature Summary

Automotive qualification compliant with AEC-Q100 standards for reliability
Adjustable output voltage via external resistors across a wide range
High precision performance with 1% initial accuracy tolerance
Low output impedance suitable for stable reference applications

Applications

Automotive power supply regulation circuits
Precision voltage references in vehicle electronics
Feedback control loops in DC-DC converters
Battery management system monitoring

Procurement Notes

Verify the complete part number including the G4 suffix to ensure RoHS compliance and lead-free status. Confirm the automotive grade designation (AQ) matches specific vehicle certification requirements. Check datasheet revisions for any pinout or electrical parameter updates before finalizing procurement specifications.

Selection Notes

Select this component when automotive reliability and high precision are required in compact surface-mount designs. The SOT-23-3 package offers space efficiency compared to larger alternatives. Ensure input voltage limits and thermal conditions align with the specified operating range for optimal performance.

Part Context

This device belongs to the TL431 family of programmable shunt regulators. The AQ prefix indicates automotive qualification, while the DBZR suffix specifies the SOT-23-3 package and tape-and-reel delivery method. It serves as a standard reference solution for replacing discrete zener diodes in precision regulation tasks.

Replacement Considerations

Direct substitutes include TL431AQDBZR without the G4 suffix. Verify package compatibility and electrical specifications against original design requirements before substitution.
