TL1431QDRG4Q1

Overview

The TL1431QDRG4Q1 is an automotive-grade adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a cathode voltage range of 2.5 V to 36 V and provides an initial accuracy of 0.4%. The device supports a maximum cathode current of 100 mA and maintains operation across an extended temperature range from -40°C to +125°C. Packaged in an 8-pin SOIC (D) surface-mount housing, it complies with AEC-Q100 standards for automotive applications.

Feature Summary

Automotive qualification compliant with AEC-Q100 standards
High precision adjustable shunt regulation topology
Extended industrial temperature range capability

Applications

Automotive power supply feedback loops
Battery management system monitoring
Precision voltage regulation in vehicle electronics

Procurement Notes

Verify the complete part number including the Q1 suffix to confirm automotive grade status. Ensure the G4 suffix indicates lead-free and RoHS compliance. Confirm the SOIC-8 package variant matches the design footprint. Validate that the 0.4% initial accuracy meets specific circuit tolerance requirements before finalizing procurement.

Selection Notes

Select this component when automotive reliability and high precision are required. The 0.4% accuracy offers tighter tolerance than standard commercial variants. The wide operating temperature range suits harsh automotive environments. Consider the 100 mA sink current capacity for load requirements. Verify compatibility with existing PCB footprints for the SOIC-8 package.

Part Context

This device belongs to the TL1431 family of adjustable shunt references. The Q1 designation specifically denotes automotive qualification under AEC-Q100 standards. The G4 suffix indicates lead-free construction and environmental compliance. It serves as a high-reliability alternative to commercial voltage references in critical automotive systems.

Replacement Considerations

The TL1431QDRQ1 is a verified substitute offering identical electrical specifications and automotive qualification. Both parts share the same SOIC-8 package and functional characteristics. Verify pinout compatibility during replacement to ensure seamless integration.
