1N5406

Overview

The Diotec Semiconductor 1N5406 is a silicon rectifier diode designed for general-purpose applications. It features an average forward rectified current of 3 A and a maximum repetitive peak reverse voltage of 600 V. The device utilizes a DO-201AD axial through-hole package with an isolated case connection. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 180 A, a typical forward voltage drop of 1.2 V at 3 A, and a low reverse leakage current of 5 µA at 600 V. The junction temperature range extends from -55 °C to +175 °C, ensuring reliable operation in demanding environments.

Feature Summary

• Low forward voltage drop for efficient power conversion
• High forward surge current capability for transient protection
• Low leakage current to minimize standby losses
• Molded epoxy body compliant with UL 94 V-0 flammability ratings

Applications

• General purpose rectification in power supplies
• Inverter and converter circuits
• Freewheeling diode applications

Procurement Notes

Verify the specific manufacturer part number against official Diotec Semiconductor documentation to confirm compliance with RoHS directives and lead-free specifications. Ensure the selected variant matches the required DO-201AD package dimensions and terminal solderability standards. Cross-reference datasheet parameters such as thermal resistance and surge ratings with actual circuit requirements before finalizing procurement decisions.

Selection Notes

Select this component when a robust standard recovery rectifier is needed for medium-power AC-to-DC conversion. The 600 V rating provides sufficient margin for common mains voltages. Consider the 175 °C maximum junction temperature for high-ambient environments. Verify that the 3 A continuous current rating aligns with the load profile and derating requirements specified in the application design.

Part Context

This component belongs to the 1N54 series of general-purpose silicon rectifiers. It shares mechanical and functional similarities with other members of the family, differing primarily in reverse voltage ratings. The DO-201AD package is a standard industry form factor for axial leaded diodes, facilitating easy integration into through-hole printed circuit boards and heat sink mounting configurations.

Replacement Considerations

Equivalent parts include Vishay 1N5406-E3/51 and Diodes Incorporated 1N5406G-T. Verify pinout compatibility and ensure replacement devices meet or exceed the original 600 V reverse voltage and 3 A forward current specifications.
