TL431AQDBZRVL

Overview

The TL431AQDBZRVL is a three-terminal adjustable precision shunt regulator manufactured by Nexperia. It operates within an output voltage range of 2.495 V to 36 V, set by two external resistors. The device features A-grade reference voltage tolerance of ±1% and meets AEC-Q100 Grade 1 automotive standards. It provides a typical temperature drift of 9 mV (0°C to 70°C) and supports sink currents from 1 mA to 100 mA with a typical output impedance of 0.2 Ω. The component is housed in a SOT-23-3 surface-mount package.

Feature Summary

AEC-Q100 qualified for Grade 1 automotive applications
Adjustable output voltage up to 36 V via external resistors
Low output noise and low output impedance
High current sink capability ranging from 1 mA to 100 mA

Applications

Shunt regulators
Precision current limiters
Isolated feedback loops for Switch Mode Power Supplies (SMPS)

Procurement Notes

Verify the specific suffix 'VL' against official Nexperia documentation to confirm reel specifications and tape-and-reel dimensions. Ensure the part number matches the required AEC-Q100 Grade 1 qualification and SOT-23-3 packaging format. Confirm availability status as supply constraints may apply to this specific variant.

Selection Notes

Select this component when high accuracy is required in automotive environments due to its AEC-Q100 Grade 1 certification. The ±1% tolerance suits precision applications where standard grades are insufficient. Consider the SOT-23-3 package for space-constrained PCB layouts requiring surface-mount technology.

Part Context

This part belongs to the TL431 family of programmable zener diodes. It serves as a drop-in replacement for legacy discrete Zener diodes in regulation circuits. The 'Q' designation indicates automotive qualification, while 'A' specifies the tighter 1% initial accuracy compared to standard grades.

Replacement Considerations

Compatible substitutes include TL431ACDBZR and TL431BIDBZR for non-automotive use. For direct automotive equivalents, consider TL431BQDBZR or TL431CQDBZR depending on required tolerance levels.
