Procurement Notes

Verify the specific E-Line 3-pin reversed package configuration (suffix R) against schematic requirements. Confirm that the ±3% tolerance aligns with system accuracy needs. Ensure operating current remains within the 20μA to 5mA recommended range for optimal performance. Check datasheet for absolute maximum ratings regarding reverse and forward currents.

Selection Notes

Select this component when space-saving through-hole packaging is required alongside low power consumption. The E-Line 3-pin reversed variant suits designs needing specific pinout orientations. Consider the ±3% tolerance if higher precision variants are not necessary. Verify thermal dissipation limits within the target enclosure environment.

Part Context

This part belongs to the ZRC250 series of precision voltage references manufactured by Diodes Incorporated. The series includes various packages such as SOT23, SO8, and E-Line styles with different tolerance options. The ZRC250R03 specifically denotes the E-Line 3-pin reversed package with ±3% accuracy.

Replacement Considerations

Compatible substitutes include other ZRC250 series parts like ZRC250F03 or ZRC250N803, provided package differences are accommodated. Cross-reference electrical parameters such as temperature coefficient and noise voltage before substitution.
