1N5524BUR-1/TR

Overview

The 1N5524BUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA (SMB) package. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device operates within a junction temperature range of -65°C to +175°C. Key electrical characteristics include a test current of 3 mA, a Zener impedance of 30 Ohms, and a maximum reverse leakage current of 2 µA at 3 V. The component is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation with a nominal Zener voltage of 5.6 V
• Supports high-temperature operation up to 175°C junction temperature
• Utilizes a compact surface-mount DO-213AA package for automated assembly

Applications

• Voltage reference circuits requiring precise regulation
• Over-voltage protection stages in electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the complete part number including the /TR suffix to confirm tape-and-reel packaging configuration. Ensure compatibility with the DO-213AA footprint during PCB layout. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when a 5.6 V regulation point is required in a surface-mount design. The 500 mW power rating suits low-current applications. Verify that the 30 Ohm impedance meets circuit noise requirements. The wide operating temperature range supports harsh environment deployments.

Part Context

This device belongs to the 1N5524 series of Zener diodes from Microchip Technology. It shares functional similarities with other components in the 1N55xx family but differs in specific voltage ratings and package types. The BUR-1 designation typically indicates specific manufacturing lot or revision details within the product line.

Replacement Considerations

The non-reel version 1N5524BUR-1 is a parameter-equivalent alternative. Cross-reference with other 5.6 V Zener diodes in the DO-213AA package if supply constraints exist.
