ZXRE4041ERSTZ

Overview

The ZXRE4041ERSTZ is a micropower voltage reference IC manufactured by Diodes Incorporated, utilizing a bandgap circuit to deliver a precise 1.225V output. It operates within a current range of 30µA to 12mA and features a typical temperature coefficient of 20ppm/°C. The device is housed in an SOT-23 surface-mount package and offers unconditionally stable performance with high capacitive load tolerance.

Feature Summary

• Provides a precision 1.225V reference using a bandgap circuit design
• Operates efficiently with a low knee current of 30µA
• Maintains stability under varying capacitive loads
• Features a compact SOT-23 surface-mount package

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems
• A/D and D/A converters

Procurement Notes

Verify the specific suffix 'ERSTZ' against official manufacturer documentation to confirm exact tolerance grade and reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23 package. Confirm RoHS compliance status and environmental certifications prior to final procurement decisions.

Selection Notes

Select this component when space constraints require a small SOT-23 footprint alongside precise voltage referencing. It serves as a direct pin-compatible alternative to LM4041 references. Consider its low operating current for battery-powered applications requiring extended operational life without sacrificing accuracy.

Part Context

This part belongs to the ZXRE4041 series of micropower voltage references from Diodes Incorporated. The series includes various tolerance grades (0.5%, 1%, 2%) packaged in SOT-23. All E-Line variants of this series are obsolete, making the SOT-23 versions the primary available option for new designs.

Replacement Considerations

The datasheet identifies the ZXRE4041 as a pin-for-pin compatible alternative to LM4041 voltage references. Verify electrical characteristics match the original design requirements before substitution.
