1N5296UR-1

Overview

The Microchip Technology 1N5296UR-1 is a current regulator diode designed for surface-mount applications. It operates within the DO-213AB (MELF) glass package, providing stable current regulation with a nominal value of 1.001 mA at a voltage of 100 V. The device features a power dissipation rating of 475 mW and utilizes round-end SMT construction for reliable board integration. Manufactured under military standards, it ensures consistent performance in demanding electronic circuits requiring precise current control.

Feature Summary

• Provides stable constant current regulation for circuit protection and biasing
• Utilizes robust MELF glass encapsulation for environmental resilience
• Designed for surface-mount technology to facilitate automated assembly

Applications

• Precision current limiting in sensitive electronic circuits
• Biasing elements for transistor and integrated circuit stages
• Protection against overcurrent conditions in signal paths

Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm compliance with MIL-PRF-19500/463 standards. Ensure that the DO-213AB package orientation matches the design footprint. Confirm RoHS status and lead-free requirements with the supplier prior to procurement to meet project specifications.

Selection Notes

Select this component when a fixed current source is required in a compact surface-mount form factor. The 1.001 mA output suits low-power signal conditioning tasks. Evaluate thermal management needs given the 475 mW dissipation limit. Compare against through-hole alternatives if space constraints allow for larger packages with higher power ratings.

Part Context

This part belongs to the JANS/JANTX series of radiation-hardened and military-grade semiconductors produced by Microchip. These components are engineered for high reliability in aerospace and defense environments. The 1N5296 designation indicates a specific current regulation characteristic within the broader family of Zener and regulator diodes offered by the manufacturer.

Replacement Considerations

Direct substitutes include JANTX1N5296UR-1 for enhanced quality screening levels. Verify pinout compatibility and electrical tolerances before substituting with generic 1N5296 equivalents. Ensure any replacement maintains the MELF package profile and meets the required military qualification standards.
