1N5530BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5530BUR-1 is a low voltage avalanche Zener diode with a nominal breakdown voltage of 10 V. It operates within the 1N5518BUR-1 through 1N5546BUR-1 series and features a hermetically sealed DO-213AA MELF surface mount package. The device provides a maximum steady-state power dissipation of 0.5 W and includes an internal metallurgical bond option. It is qualified per MIL-PRF-19500/437 for JAN, JANTX, and JANTXV reliability levels.

Single Zener Diodes Feature Summary

• Hermetically sealed glass surface mount construction in a DO-213AA MELF package
• Internal metallurgical bond for enhanced structural integrity
• Qualified to MIL-PRF-19500/437 standards for military reliability grades
• Inherently radiation hard design suitable for aerospace environments

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Satellite communications (satcom) systems
• Aerospace and defense electronic circuits
• High-reliability surface mount assemblies

Single Zener Diodes Procurement Notes

Verify that the specific order includes the UR-1 suffix to ensure the inclusion of the internal metallurgical bond feature. Confirm the required reliability level (JAN, JANTX, or JANTXV) matches the application's environmental specifications. Ensure the procurement documentation explicitly references MIL-PRF-19500/437 qualification requirements.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener regulator is required for high-reliability applications. The DO-213AA package is appropriate for automated assembly processes. Consider the radiation hardness characteristics if the deployment environment involves ionizing radiation exposure.

Single Zener Diodes Part Context

This part belongs to the 1N5518BUR-1 through 1N5546BUR-1 series of low voltage avalanche Zener diodes manufactured by Microchip Technology. The series covers a voltage range from 3.3 V to 33 V. These devices are designed as direct replacements for standard JEDEC registered 1N5518 through 1N5546 types but offer superior packaging and reliability options.

Single Zener Diodes Replacement Considerations

Standard commercial versions without the UR-1 suffix lack the internal metallurgical bond. Verify compatibility with existing board footprints for the DO-213AA package.
