1N5524UR-1

Overview

The Microchip Technology 1N5524UR-1 is a single silicon Zener diode designed for surface-mount applications. It features a nominal Zener voltage of 5.6V with a tolerance of ±20% and a maximum power dissipation of 500 mW. The device utilizes a DO-213AA (MLL34) glass MELF package, which is hermetically sealed. Electrical characteristics include a reverse leakage current of 2 μA at the rated voltage. This component is part of the low-voltage surface mount avalanche diode series, offering robust performance in regulated voltage circuits.

Feature Summary

• Hermetically sealed glass MELF construction for environmental stability
• Internal metallurgical bond option available within the series
• Surface-mount design compatible with automated assembly processes

Applications

• Voltage regulation in military-grade electronic systems
• Clamping and protection circuits requiring stable reference voltages
• Low-power surface-mount board designs

Procurement Notes

Verify that the specific order matches the non-RoHS status indicated in official documentation. Confirm the package type is DO-213AA and ensure the voltage rating aligns with system requirements. Check for any suffix variations that may indicate different tolerance levels or bonding options. Validate manufacturer authenticity through authorized channels to prevent counterfeit components.

Selection Notes

Select this component when a 5.6V reference is required in a compact surface-mount form factor. Consider the 20% tolerance if precise voltage regulation is not critical. Evaluate the 500 mW power rating against thermal constraints in the final assembly. Ensure compatibility with existing PCB footprints for the DO-213AA package.

Part Context

This part belongs to the 1N55xx series of low-voltage surface mount Zener diodes manufactured by Microchip Technology. The series spans from 3.3V to 33V, providing various tolerance options. The UR-1 designation typically indicates a specific packaging or qualification variant within the broader product line, often associated with military or high-reliability standards.

Replacement Considerations

Direct substitutes include other 1N5524 variants with matching voltage and power ratings. Verify package compatibility before substitution. Cross-reference with JANTX1N5524URTR for similar specifications. Ensure replacement parts meet the same hermetic sealing and material requirements.
