1N5404

Overview

The Lumimax Optoelectronic Technology 1N5404 is a general-purpose silicon rectifier diode housed in a DO-201AD (DO-27) axial leaded package. It features a maximum repetitive peak reverse voltage of 400 V and supports a maximum average forward rectified current of 3.0 A at 25°C ambient temperature. The device exhibits a maximum instantaneous forward voltage of 1.1 V and a maximum DC reverse current of 5 μA at rated blocking voltage. It withstands a peak forward surge current of 200 A for an 8.3 ms half-sine wave. Operating and storage temperatures range from -50°C to +150°C, with a typical junction capacitance of 50 pF.

Feature Summary

• Low forward voltage drop for efficient power conversion
• Low leakage current characteristics
• High forward surge current capability
• Guaranteed high-temperature soldering performance

Applications

• General purpose rectification in AC/DC converters
• Freewheeling diodes in inductive load circuits
• Power supply input stages

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N5404 specification is widely utilized by multiple semiconductor producers. Confirm that the received component matches the Lumimax Optoelectronic Technology datasheet Rev 1.1 requirements regarding the DO-201AD package dimensions and terminal plating specifications. Ensure compliance with RoHS and REACH directives if required by your assembly process.

Selection Notes

Select this component for applications requiring robust standard recovery performance with a 400 V reverse voltage rating. It is suitable for circuits demanding a 3 A continuous current capacity with high surge tolerance. Consider the thermal resistance of 30 °C/W and the requirement to derate current by 20% when used with capacitive loads to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the 1N5400 through 1N5408 series of glass-passivated silicon rectifiers. The series shares identical current and surge ratings, differing only in their maximum repetitive peak reverse voltage ratings which range from 50 V to 1000 V. The 1N5404 specifically provides the 400 V rating within this standardized family.

Replacement Considerations

Compatible substitutes include Vishay 1N5404-E3/54, Rectron 1N5404GU27, and SMC 1N5404TA. Verify that replacement parts maintain the DO-201AD package form factor and meet the 3 A current and 400 V voltage specifications.
