1N5552E3

Overview

The Microchip Technology 1N5552E3 is a standard recovery rectifier diode designed for through-hole mounting. It features a single configuration with a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 3 A. The device exhibits a maximum forward voltage drop of 1.2 V at rated current and a typical reverse leakage current of 1 uA. It supports a maximum surge current of 100 A and operates within a junction temperature range of -65 °C to +175 °C. The component utilizes a DO-41 axial leaded package.

Feature Summary

• Glass passivated junction construction for reliable operation under high temperature conditions
• Hermetically sealed package design ensuring environmental stability
• Capable of meeting MIL-S-19500 environmental standards

Applications

• General purpose rectification in power supply circuits
• High temperature industrial control systems
• Automotive electronics requiring robust diode performance

Procurement Notes

Verify the specific suffix E3 indicates RoHS compliance when sourcing. Confirm the manufacturer designation as Microchip Technology or its predecessor entities like Vishay or GE Sensing, as historical data may vary. Ensure the package type matches the required PCB footprint for axial leads. Check for recent Product Change Notifications regarding material updates.

Selection Notes

Select this component for applications requiring standard recovery characteristics rather than fast switching. The 600 V rating provides sufficient margin for common AC line voltages. Consider the thermal management requirements given the 175 °C maximum junction temperature capability. Verify that the 3 A continuous current rating meets the circuit load demands without excessive derating.

Part Context

This part belongs to the 1N55xx series of glass passivated silicon rectifiers. It is functionally similar to other industry-standard parts but manufactured to specific military-grade reliability criteria. The series offers various voltage ratings from 200 V to 1000 V while maintaining consistent current handling capabilities.

Replacement Considerations

Direct substitutes include 1N5552 variants from other manufacturers such as Vishay or ON Semiconductor. Ensure any replacement maintains the same DO-41 package and glass passivation technology for equivalent thermal and electrical performance.
