1N5284UR-1

Overview

The JAN1N5284UR-1 is a current regulator diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AB-2 package. It provides a regulated current of 264 µA with a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. The device operates within an extended temperature range from -65°C to +175°C. This component belongs to the 1N5284 series and is classified under Diodes & Rectifiers. It features round-end SMT construction suitable for automated assembly processes.

Feature Summary

• Maintains constant current output regardless of voltage fluctuations within specified limits
• Supports high-temperature operation up to 175°C for demanding environments
• Utilizes compact surface-mount packaging for space-constrained designs

Applications

• Biasing circuits for transistors and integrated circuits
• LED current regulation in display systems
• Constant current sources for sensor interfaces

Procurement Notes

Verify compliance requirements as the JAN1N5284UR-1 is marked non-RoHS. Confirm lead times due to reported long delivery durations and potential production delays. Ensure the specific military-grade JAN prefix variant matches design specifications rather than commercial equivalents. Validate package integrity upon receipt given the small form factor.

Selection Notes

Select this component when precise low-current regulation is required in harsh thermal conditions. Compare against the CD5284 for similar electrical characteristics but different packaging options. Consider the 1N5283-1 if through-hole mounting is preferred instead of surface mount. Ensure the 100V breakdown voltage exceeds the maximum circuit voltage to prevent device failure.

Part Context

This part is part of the broader 1N528x series of current regulator diodes produced by Microchip Technology. It shares functional similarities with other members like the 1N5283 and 1N5285 but differs in regulated current values and physical package types. The JAN designation typically indicates a higher reliability or military-grade version compared to standard commercial parts.

Replacement Considerations

The CD5284 serves as a direct functional substitute with identical electrical parameters but may differ in packaging configuration. Verify pinout compatibility and thermal performance before substitution. Other series members like the 1N5283 offer similar regulation but require checking specific current ratings.
