JANTX1N5314UR-1/TR

Current Regulation - Diodes, Transistors Overview

The JANTX1N5314UR-1/TR is a current regulator diode manufactured by Microchip Technology. It provides a regulated current of 5.17 mA with a maximum reverse voltage rating of 100 V and a power dissipation capacity of 500 mW. The device utilizes a surface-mount DO-213AB-2 package, also known as MELF, featuring round-end terminals for automated assembly. This component belongs to the military-grade JANTX series, designed for stable current regulation across a broad voltage range in compact axial-equivalent form factors.

Current Regulation - Diodes, Transistors Feature Summary

• Provides constant current regulation over a wide operating voltage range
• Utilizes a compact surface-mount MELF package equivalent to axial leads
• Qualified to MIL-PRF-19500/463 standards for high-reliability applications

Current Regulation - Diodes, Transistors Applications

• Constant current sources for LED driving circuits
• Biasing elements for transistor amplifier stages
• Current limiting protection in sensitive electronic loads

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix configuration when ordering. The -1 suffix typically denotes a round-end terminal style for the MELF package, while /TR indicates tape-and-reel packaging. Confirm that the JANTX grade meets the required radiation hardness and reliability specifications for the intended mission profile before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required within a limited PCB area. Ensure the supply voltage exceeds the minimum dropout voltage to maintain regulation. Compare against standard commercial equivalents if military qualification is not mandatory, noting that JANTX parts undergo stricter screening processes than commercial variants.

Current Regulation - Diodes, Transistors Part Context

This part is part of the 1N53xx series of current regulator diodes. These devices function similarly to Zener diodes but regulate current instead of voltage. The JANTX variant offers tighter tolerance and higher reliability than JAN parts, suitable for aerospace and defense systems requiring proven performance under harsh environmental conditions.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct replacements include other JANTX1N5314 variants with compatible packaging. Verify terminal style (flat vs. round) and reel quantity. Commercial equivalents like the 1N5314 exist but lack military screening. Cross-reference datasheets for exact current tolerance and breakdown voltage limits.
