1N4004-T

Single Diodes Overview

The Lumimax Optoelectronic Technology 1N4004-T is a general-purpose silicon rectifier diode designed for standard recovery applications. It features a DO-204AL (DO-41) axial lead package with transfer molded plastic construction. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1.0 A. Key electrical parameters include a maximum instantaneous forward voltage of 1.1 V, a peak forward surge current capability of 30 A, and a maximum DC reverse current of 50 μA at rated blocking voltage. The component operates within a junction temperature range of -50°C to +150°C.

Single Diodes Feature Summary

• Low forward voltage drop for efficient power conversion
• High forward surge current capability for transient protection
• Guaranteed high-temperature soldering performance up to 260°C
• Compliant with RoHS and REACH environmental standards

Single Diodes Applications

• General purpose rectification in AC/DC power supplies
• Polarity protection circuits
• Freewheeling diodes in inductive load switching

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as the 1N4004-T suffix indicates production by Lumimax Optoelectronic Technology. Confirm that the required package is DO-204AL and check datasheet revisions for any updates to mechanical dimensions or thermal characteristics. Ensure compliance with project-specific environmental regulations such as RoHS and REACH before finalizing procurement.

Single Diodes Selection Notes

Select this component for applications requiring a 400V reverse voltage rating and 1A continuous current handling. It is suitable for designs needing robust surge immunity up to 30A. Consider the operating temperature range of -50°C to +150°C for environmental suitability. Verify that the through-hole DO-41 package fits the PCB layout constraints and that the 1.1V forward voltage drop meets efficiency requirements.

Single Diodes Part Context

This part belongs to the 1N4001–1N4007 series of general-purpose silicon rectifiers. These devices share identical physical packages and average forward current ratings but differ primarily in their maximum repetitive peak reverse voltage ratings, which range from 50V to 1000V across the series. The 1N4004 variant specifically targets 400V blocking applications.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4004 parts in the DO-41 package, such as those from onsemi, Micro Commercial Components, or Fairchild. Ensure replacement parts match the 400V VRRM, 1A IF(AV), and 30A IFSM specifications.
