1N5407

Overview

The Diotec Semiconductor 1N5407 is a standard recovery rectifier diode designed for general-purpose applications. It features a silicon construction housed in an isolated DO-201 axial leaded package. The device supports a maximum average forward rectified current of 3A and offers a repetitive peak reverse voltage rating of 800V. Key electrical characteristics include a low leakage current of 5µA at the rated voltage, a typical forward voltage drop of 1.2V at full load, and a reverse recovery time of 1.5µs. It operates within a junction temperature range of -50°C to +175°C.

Feature Summary

• Glass passivated chip junction for enhanced environmental stability
• High surge current capability for robust transient protection
• Low leakage current ensuring minimal power loss
• Molded case with UL-94 V-0 flammability rating

Applications

• General purpose rectification circuits
• Free wheeling diodes in inductive loads
• Polarity protection in DC power supplies

Procurement Notes

Verify the specific manufacturer suffix or lot code against the required datasheet revision, as Diotec may update component markings over time. Confirm that the DO-201 package dimensions match your PCB footprint requirements. Ensure the ordering part number explicitly includes the Diotec designation to distinguish from generic equivalents. Check for RoHS compliance status if restricted substances are prohibited in your assembly process.

Selection Notes

Select this component when an 800V blocking voltage is necessary for high-voltage AC-to-DC conversion or flyback topologies. The 3A continuous current rating suits moderate power applications where thermal management is feasible. Consider the 1.5µs reverse recovery time; it is suitable for line-frequency operations but may generate excessive switching losses in high-frequency converters exceeding several kilohertz.

Part Context

This device belongs to the 1N54xx series of glass-passivated rectifiers manufactured by Diotec Semiconductor. It shares the same physical package and current handling capabilities as lower-voltage variants like the 1N5404 (400V) and 1N5406 (600V). The series provides a standardized solution for replacing legacy components in industrial and consumer electronics designs requiring reliable high-voltage rectification.

Replacement Considerations

Direct substitutes include Vishay 1N5407 and Taiwan Semiconductor 1N5407GHA0. Verify that replacement parts maintain the 800V reverse voltage and 3A current ratings. Ensure the alternative supplier's DO-201 package dimensions are compatible with existing board layouts.
