1N5404-A

Overview

The 1N5404-A is a standard recovery rectifier diode manufactured by Diodes Incorporated. It features a single-phase, one-element silicon construction housed in a DO-201AD axial through-hole package. The device supports a maximum average forward rectified current of 3 A and a maximum repetitive peak reverse voltage of 400 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 200 A and a low reverse leakage current of 5 µA at rated voltage. The component operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• High forward surge current capability for robust transient protection
• Low reverse leakage current ensuring efficient blocking performance
• Mechanical data compliant with UL flammability classification 94V-0

Applications

• General purpose rectification in power supply circuits
• Freewheeling diode applications in inductive load management
• Half-wave rectification in resistive or inductive AC-to-DC conversion

Procurement Notes

Verify the specific suffix 'A' against official Diodes Incorporated documentation to confirm if it denotes a specific tape-and-reel packaging variant or a distinct electrical grade compared to the standard 1N5404. Ensure the selected part number matches the required RoHS compliance status and lead-free specifications for your assembly process.

Selection Notes

Select this component when a high-current, high-voltage through-hole rectifier is required for general-purpose applications. The 3 A rating and 400 V breakdown voltage make it suitable for mains-frequency rectification. Consider the thermal derating requirements for capacitive loads and ensure the PCB layout accommodates the DO-201AD package dimensions and lead spacing.

Part Context

This component belongs to the widely recognized 1N54xx series of silicon rectifiers. The 1N5404 specifically provides a 400 V reverse voltage rating, distinguishing it from lower-voltage variants like the 1N5401 (50 V) or higher-voltage counterparts like the 1N5408 (1000 V). It serves as a standard industrial solution for medium-power rectification tasks.

Replacement Considerations

Direct substitutes include Vishay's 1N5404-E3/54, Rectron's 1N5404GU27, and LRC's 1N5404. These alternatives share identical electrical ratings and DO-201AD mechanical footprints, allowing for pin-compatible replacement in existing designs.
