JANTXV1N5292UR-1/TR

Overview

The JANTXV1N5292UR-1/TR is a current regulator diode manufactured by Microchip Technology. It operates within a voltage range of 100 V and maintains a regulated current of 682 µA. The device has a power dissipation rating of 475 mW. It utilizes the DO-213AB-2 package, also known as MELF, for surface-mount installation. This component is designed for applications requiring stable current regulation in harsh environments.

Feature Summary

• Provides constant current regulation with low dynamic impedance
• Hermetically sealed glass encapsulation for environmental protection
• Round-end terminal design compatible with automated assembly

Applications

• Current limiting in sensitive electronic circuits
• Biasing elements for transistor amplifiers
• Protection against overcurrent conditions in aerospace systems

Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration. Confirm RoHS compliance status as military-grade variants often differ from commercial standards. Validate that the DO-213AB-2 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a precise 682 µA regulation is required at up to 100 V reverse bias. Ensure the application can accommodate the 475 mW power dissipation limit. Compare against standard commercial equivalents if hermetic sealing is not strictly necessary for the operational environment.

Part Context

This part belongs to the JANTXV series of radiation-hardened or high-reliability semiconductors produced by Microchip. The 1N5292 designation identifies the specific current regulation characteristics. The UR-1 suffix typically denotes the round-end MELF package style used in military and aerospace electronics manufacturing.

Replacement Considerations

Direct substitutes include the JANS1N5292UR-1 for space-grade applications or the JANTX1N5292UR-1 for general high-reliability use. Verify electrical parameter tolerances and package compatibility before swapping between these related part numbers.
