1N5525B-1/TR

Overview

The Microchip Technology 1N5525B-1/TR is a standard rectifier diode designed for general-purpose applications. It features a glass passivated junction and utilizes the DO-35 axial leaded package. The device provides a maximum average forward rectified current of 1.0 A at specified temperatures. Key electrical characteristics include a peak repetitive reverse voltage rating of 100 V and a non-repetitive peak forward surge current capability. The component is engineered to offer reliable performance in low-power rectification circuits with stable thermal properties.

Feature Summary

• Glass passivated junction construction for enhanced reliability
• Standard axial leaded package for through-hole mounting
• High surge current capability for transient protection

Applications

• General-purpose rectification in power supplies
• Protection circuits against reverse polarity
• Low-frequency switching applications

Procurement Notes

Verify the specific suffix -1/TR confirms the tape and reel packaging format when ordering. Ensure the procurement documentation matches the exact part number to avoid confusion with similar variants lacking the trailing slash or different suffixes. Confirm that the supplier source provides traceability to Microchip Technology manufacturing standards. Check for any specific handling requirements related to the axial leaded form factor during assembly.

Selection Notes

Select this component when a robust, standard recovery rectifier is required for currents up to 1.0 A. Consider the 100 V reverse voltage rating to ensure adequate margin for the circuit's peak inverse voltage. Evaluate the thermal resistance and operating temperature range to match the environmental conditions of the application. Compare the forward voltage drop characteristics against other diodes if efficiency is a critical design constraint.

Part Context

This part belongs to the 1N55xx series of glass passivated silicon rectifiers from Microchip Technology. These components are widely used in industrial and consumer electronics where reliable, low-cost rectification is needed. The series offers various voltage ratings to suit different circuit requirements while maintaining consistent mechanical and electrical performance standards across the product line.

Replacement Considerations

Cross-reference with other 1N5525B equivalents from different manufacturers ensuring identical DO-35 package dimensions and electrical ratings. Verify that substitute parts meet the same glass passivation and surge current specifications. Confirm compatibility with existing PCB footprints and soldering processes before implementation.
