1N5285UR-1

Overview

The Microchip Technology 1N5285UR-1 is a current regulator diode designed for surface-mount applications. It operates within the DO-213AB (MELF) package, providing a regulated current of 279 µA with a maximum limiting voltage of 1 V and a peak operating voltage of 100 V. The device supports a power dissipation of 500 mW and functions across an extended temperature range from -55 °C to +175 °C. This component belongs to the MIL-PRF-19500/463 military series, ensuring reliability in demanding environments.

Feature Summary

Hermetically sealed glass MELF package for environmental protection
Constant current regulation capability for circuit stability
Extended high-temperature operation up to 175 °C

Applications

Military aerospace electronic systems
High-reliability industrial instrumentation
Precision constant current biasing circuits

Procurement Notes

Verify the specific ordering suffix UR-1 against the official Microchip datasheet to confirm the exact package variant and testing standards. Ensure compliance with MIL-PRF-19500/463 requirements if the application mandates military-grade specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability documentation.

Selection Notes

Select this component when a hermetically sealed surface-mount current regulator is required for high-temperature or harsh environments. Compare the 279 µA regulation point against circuit load requirements to ensure proper biasing. Verify that the DO-213AB footprint matches the PCB design constraints and thermal management strategy.

Part Context

This device is part of the broader 1N5285 family of current regulator diodes manufactured by Microchip Technology. Variants such as JANTX1N5285UR-1 share similar electrical characteristics but may differ in screening levels or packaging details. The 1N5285UR-1 specifically denotes the standard commercial or qualified version within this product line.

Replacement Considerations

Direct substitutes include JAN1N5284UR-1 for lower current applications or JANTX1N5285UR-1 for enhanced military screening. Verify pinout compatibility and thermal resistance values before substitution.
