Overview
The Nexperia TL431BMFDT/8VL is an adjustable shunt voltage reference in a SOT-23-3 surface-mount package. It provides a reference voltage of 2.5 V with an initial accuracy of ±0.5%. The device supports a cathode current up to 100 mA and withstands a maximum input voltage of 37 V. It operates within a temperature range of -40°C to +125°C. Qualified under AEC-Q100 standards, it features low dynamic output impedance and line regulation of -2.7 mV/V.
Feature Summary
- Adjustable shunt topology for precise voltage referencing
- Automotive-grade qualification ensuring reliability in harsh environments
- Compact SOT-23-3 surface-mount packaging for space-constrained designs
Applications
- Precision power supply regulation circuits
- Portable equipment voltage monitoring
- Battery-powered system references
Procurement Notes
Verify the specific suffix (8VL) against the manufacturer's latest datasheet to confirm tape-and-reel specifications and pinout orientation. Ensure the selected variant meets the required automotive grade and temperature range for your application environment before finalizing procurement.
Selection Notes
Select this component when high precision and automotive reliability are required in a small footprint. The ±0.5% accuracy suits applications needing stable reference voltages without external trimming. Consider the 37 V max input limit and 100 mA current capability when designing the biasing network.
Part Context
This part belongs to the TL431 series, a widely used family of programmable shunt regulators. The TL431BMFDT/8VL variant specifically targets automotive and industrial markets, offering enhanced stability and temperature performance compared to standard commercial grades while maintaining compatibility with legacy designs.
Replacement Considerations
Compatible substitutes include the TL431BFDT,215 and TL431BMFDT,215 from Nexperia, which share similar electrical characteristics and package dimensions. Verify pinout compatibility and thermal performance when transitioning between these variants.
