JAN1N5537DUR-1/TR

Single Zener Diodes Overview

The JAN1N5537DUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 17 V with a tight tolerance of 1%. The device operates in the SMD/SMT configuration within a DO-213AA-2 package and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 10 nA and a Zener impedance of 100 Ohms at a test current of 1 mA. It supports an extended operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 1% tolerance on the 17 V Zener voltage.
• Engineered for high-reliability environments with an extended operating temperature range up to 175°C.
• Utilizes a compact surface-mount DO-213AA-2 package for automated assembly integration.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection systems
• Military and aerospace electronic assemblies

Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm the exact reel quantity and packaging configuration. Ensure compatibility with the target PCB footprint for the DO-213AA-2 package. Confirm that the 1% tolerance meets the design requirements for the intended voltage regulation application before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 17 V reference is required in a surface-mount format. The 1% tolerance offers higher precision than standard commercial variants. Consider the 500 mW power dissipation limit and the wide temperature range suitability for harsh environment deployments where standard industrial parts may fail.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology, formerly Microsemi. The JAN designation typically indicates qualification for military or high-reliability standards. It shares the core 1N5537 electrical profile but is packaged for surface-mount technology rather than through-hole, distinguishing it from axial lead equivalents like the 1N5537D.
