Procurement Notes
Verify the component status as this specific part number may be discontinued or obsolete. Confirm availability through authorized distributors or check for valid replacement alternatives if sourcing new inventory is required. Ensure compliance with RoHS specifications and verify package markings against official ordering information.
Selection Notes
Select this component for applications requiring a precise 5.0 V reference in space-constrained designs using SO-8 packages. It is suitable for low-power and battery-operated systems due to its micropower characteristics. Consider the ±2% tolerance and 20 ppm/°C temperature coefficient when designing circuits that demand high stability over varying thermal conditions.
Part Context
This component belongs to the ZR4040 series of precision voltage references produced by Diodes Incorporated. The series includes variants with different tolerances (1% and 2%) and package options such as SOT-23 and TO-92. The ZR40402N850TA specifically denotes the 2% tolerance version in the SO-8 surface-mount configuration.
Replacement Considerations
Public confirmed substitute: REF5050ID (Texas Instruments).
