1N5552E3/TR

Overview

The Microchip Technology 1N5552E3/TR 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 current rating of 3 A. The device utilizes a DO-41 (DO-204AH) axial leaded package, typically supplied in tape and reel format. Key electrical characteristics include a maximum DC reverse leakage current of 5 µA at rated voltage and a typical forward voltage drop of 1.2 V at full load. It supports a non-repetitive peak forward surge current of 100 A and operates within a junction temperature range from -65°C to +175°C.

Feature Summary

• Glass passivated junction construction provides reliable performance under high-temperature conditions.
• Capable of meeting environmental standards defined by MIL-S-19500 specifications.
• Medium switching speed design optimizes efficiency for general-purpose rectification applications.

Applications

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

Procurement Notes

Verify the specific suffix 'E3' confirms lead-free compliance and RoHS status against the manufacturer's latest datasheet. Confirm the 'TR' designation indicates tape-and-reel packaging rather than bulk units. Ensure the ordering quantity aligns with the manufacturer's minimum reel size requirements to avoid partial reel handling issues.

Selection Notes

Select this component when a 600 V reverse voltage rating and 3 A continuous forward current are required. The axial leaded package facilitates easy insertion into printed circuit boards or terminal blocks. Consider the 175°C maximum operating temperature for environments exceeding standard industrial limits.

Part Context

This part belongs to the 1N55xx series of glass-passivated silicon rectifiers manufactured by Microchip Technology. The series offers various voltage ratings ranging from 200 V to 1000 V while maintaining a consistent 3 A forward current capability across all variants.

Replacement Considerations

Direct equivalents include the 1N5552B and 1N5552C from other manufacturers, provided they meet the same 600 V and 3 A specifications. Verify pinout compatibility and thermal resistance values before substitution.
