1N5524BUR-1

Overview

The 1N5524BUR-1 is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5%. The device operates in a surface-mount DO-213AA-2 package and supports a maximum power dissipation of 500 mW. Key electrical characteristics include a test current of 3 mA, a maximum reverse leakage current of 2 µA at 3 V, and a Zener impedance of 30 Ohms. The component is rated for an operating temperature range from -65°C to +175°C TJ.

Feature Summary

• Provides stable voltage regulation with a nominal 5.6 V breakdown voltage.
• Capable of handling up to 500 mW of power dissipation.
• Engineered for high-temperature reliability with operation up to 175°C junction temperature.
• Utilizes a compact surface-mount DO-213AA-2 package for automated assembly.

Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in sensitive electronic systems.
• Clamping applications within signal processing paths.

Procurement Notes

Verify the specific suffix BUR-1 against official Microchip documentation to confirm the exact package variant and testing parameters. Ensure compatibility with the target PCB footprint for the DO-213AA-2 form factor. Cross-reference datasheet limits for thermal management requirements during integration.

Selection Notes

Select this component when a 5.6 V regulation point is required in a surface-mount design. Consider the 5% tolerance and 30 Ohm impedance for precision needs. Evaluate the 500 mW power rating against expected circuit loads to ensure safe operation within the specified temperature range.

Part Context

This part belongs to the Microchip 1N55xx series of Zener diodes, which are widely used for general-purpose voltage regulation. The BUR-1 designation typically indicates a specific tape-and-reel packaging configuration or manufacturing lot variation within the standard product line, distinct from bulk or axial leaded versions.

Replacement Considerations

Consult official Microchip substitution guides for parameter-equivalent alternatives. Verify that any substitute matches the 5.6 V Zener voltage, 500 mW power rating, and DO-213AA-2 package dimensions to maintain mechanical and electrical integrity.
