JANTXV1N5288UR-1/TR

Overview

The JANTXV1N5288UR-1/TR is a current regulator diode manufactured by Microchip Technology, designed for high-reliability applications. It features a maximum regulator current of 429 µA and a maximum peak operating voltage of 100 V. The device operates within an extended temperature range from -65 °C to +175 °C. Packaged in the DO-213AB MELF (LL41) format with tape-and-reel delivery, it ensures stable current regulation under harsh environmental conditions.

Feature Summary

• Provides constant current regulation suitable for precision analog circuits
• Constructed with hermetically sealed glass encapsulation for durability
• Capable of operation in extreme thermal environments up to 175 °C

Applications

• Military aerospace electronic systems requiring MIL-PRF-19500/463 compliance
• High-reliability sensor biasing circuits
• Precision current limiting in defense-grade instrumentation

Procurement Notes

Verify that the specific suffix UR-1/TR corresponds to the intended MELF package and reel quantity. Confirm military qualification status against the latest Microchip datasheet revision. Ensure compatibility with automated pick-and-place equipment due to the round-end surface mount form factor.

Selection Notes

Select this component when a fixed low-current source is required in space-constrained designs. The 429 µA rating suits sensitive signal paths. Compare against standard commercial variants if radiation hardness or wide temperature tolerance is not mandatory for the target application environment.

Part Context

This part belongs to the JAN series of current regulator diodes, which are characterized for use in ruggedized electronics. The TXV designation indicates enhanced testing levels compared to standard commercial grades, aligning with stringent military reliability standards for critical subsystems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical tolerances before considering any alternative current regulator diodes.
