ZXRE4041DRSTZ

Overview

The ZXRE4041DRSTZ is a shunt precision voltage reference manufactured by Diodes Incorporated. It provides a stable output voltage of 1.225 V with an initial accuracy of 3%. The device utilizes a bandgap circuit architecture and operates within a temperature range of -40°C to +125°C. Key electrical specifications include a maximum shunt current of 12 mA and a temperature coefficient of 100 PPM/°C. It is housed in an E-Line-3 package designed for through-hole mounting.

Feature Summary

• Provides a precise 1.225 V reference voltage using bandgap technology
• Maintains stability across extended industrial temperature ranges
• Designed for through-hole integration via E-Line-3 packaging

Applications

• Precision analog-to-digital converter reference inputs
• Calibration circuits requiring stable low-voltage references
• Power supply monitoring systems

Procurement Notes

Verify the specific suffix 'DRSTZ' against official Diodes Incorporated documentation to confirm exact tape-and-reel or bulk packaging configuration, as suffixes often dictate shipping format rather than electrical function. Ensure the requested quantity aligns with manufacturer minimum order requirements and lead times specified in current distributor catalogs. Confirm RoHS compliance status directly from the latest datasheet revision.

Selection Notes

Select this component when a 1.225 V reference is required with 3% initial accuracy. The 100 PPM/°C temperature coefficient suits applications where moderate thermal drift is acceptable. Verify that the 12 mA maximum shunt current meets the biasing requirements of the target circuit. Ensure the through-hole E-Line-3 package fits the PCB layout constraints compared to surface-mount alternatives.

Part Context

This part belongs to the ZR4040 series of shunt voltage references from Diodes Incorporated. These devices are engineered to replace older zener diodes in precision applications. The series offers various fixed voltages and accuracies, catering to general-purpose power management and signal conditioning needs within the PMIC category.

Replacement Considerations

Direct substitutes include other 1.225 V shunt references with similar accuracy and package types. Verify pinout compatibility and thermal performance before substitution. Cross-reference with LM4040 series equivalents if available, ensuring voltage tolerance and temperature coefficients match design requirements.
