TL431AQDBZR,215

Overview

The TL431AQDBZR,215 is a three-terminal adjustable precision shunt regulator manufactured by Nexperia in an SOT-23 surface-mount package. It operates within a voltage range of 2.495 V to 36 V, set via two external resistors. The device features an initial accuracy of ±1% and supports a cathode current capability from 1 mA to 100 mA. It is AEC-Q100 Grade 1 qualified for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

AEC-Q100 Grade 1 qualified for automotive reliability
Adjustable output voltage up to 36 V using external resistors
Low output impedance with sharp turn-on characteristics

Applications

Switched-mode power supply (SMPS) isolation feedback loops
Precision current limiters
On-board regulation

Procurement Notes

Verify the specific suffix

Selection Notes

Select this component when high accuracy is required in compact designs. The ±1% tolerance suits precision circuits. Ensure the design accommodates the minimum cathode current requirement for stable regulation. Verify thermal management for the SOT-23 package under maximum load conditions.

Part Context

This part belongs to the TL431 family of shunt regulators. It serves as a drop-in replacement for standard Zener diodes in many voltage reference applications. The 'Q' designation indicates automotive qualification, while 'A' specifies the 1% accuracy grade.

Replacement Considerations

Compatible substitutes include TL431ACDBZR,215 and TL431BCDBZR,215 from Nexperia. Cross-brand equivalents like the LM431 series may require verification of pinout and electrical parameter alignment.
