JAN1N4626UR-1/TR

Single Zener Diodes Overview

The JAN1N4626UR-1/TR is a single Zener diode voltage regulator manufactured by Microchip Technology. It features a nominal Zener voltage of 5.6 V with a tight tolerance of 2%. The device operates in an SMD/SMT configuration within a DO-213AA-2 package, dissipating up to 500 mW. It supports a wide operating temperature range from -65 °C to +175 °C and exhibits a maximum reverse leakage current of 5 µA at a test current of 250 µA.

Single Zener Diodes Feature Summary

• High-temperature operation capability extending to +175 °C for demanding environments
• Precision voltage regulation with 2% tolerance for stable reference applications
• Surface-mount design in a compact DO-213AA-2 package for automated assembly

Single Zener Diodes Applications

• Voltage reference circuits requiring high thermal stability
• Overvoltage protection in aerospace and defense electronics
• Precision regulation in harsh environment industrial systems

Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm surface-mount packaging and tape-and-reel delivery format. Ensure compliance requirements align with project specifications, as RoHS status may vary. Cross-reference the manufacturer part number directly with the datasheet to validate electrical parameters before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 5.6 V reference is required in a surface-mount form factor. The 2% tolerance offers tighter regulation than standard variants. Consider the DO-213AA-2 footprint constraints and the extended temperature range suitability for your specific board layout and environmental conditions.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes, designed for military and aerospace applications. The JAN designation indicates qualification to stringent reliability standards. The UR-1 suffix typically denotes a round-end axial leaded style in some contexts, but the TR suffix and Mouser data indicate a surface-mount variant, highlighting the importance of verifying the exact physical package description in the primary datasheet.

Single Zener Diodes Replacement Considerations

Consult Microchip's official substitution guide for verified equivalents. Generic replacements may not match the 2% tolerance or +175 °C rating. Verify pinout compatibility and package dimensions if considering alternative manufacturers.
