1N4004

Single Diodes Overview

The Lumimax Optoelectronic Technology 1N4004 is a general-purpose silicon rectifier diode housed in a DO-41 (DO204AL) axial leaded package. It features a maximum repetitive peak reverse voltage of 400 V and supports an average forward rectified current of 1.0 A. The device exhibits a maximum instantaneous forward voltage of 1.1 V and a typical junction capacitance of 15 pF. It withstands a peak forward surge current of 30 A and operates within a temperature range of -50 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 at 260°C
• Compliant with RoHS and REACH environmental directives

Single Diodes Applications

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

Single Diodes Procurement Notes

Verify the specific manufacturer designation, as the 1N4004 part number is widely produced by multiple semiconductor vendors including onsemi, Rectron, and others. Confirm that the supplied component matches the Lumimax Optoelectronic Technology datasheet specifications, particularly regarding the DO-41 package dimensions and electrical ratings, before integration into designs requiring strict compliance with these parameters.

Single Diodes Selection Notes

Select this component when a standard recovery rectifier with a 400 V blocking voltage and 1 A continuous current rating is required. Ensure the application environment remains within the specified -50 to +150 °C operating temperature range. Consider derating the forward current by 20% if used with capacitive loads to maintain reliability and prevent thermal overstress during operation.

Single Diodes Part Context

This component belongs to the 1N4001 through 1N4007 series of general-purpose silicon rectifiers. The series shares identical current and surge ratings but varies in reverse voltage capabilities ranging from 50 V to 1000 V. The 1N4004 specifically targets applications requiring 400 V isolation while maintaining the robust mechanical and thermal characteristics common to the entire family.

Single Diodes Replacement Considerations

Direct functional substitutes include other manufacturers' 1N4004 parts such as those from onsemi or Rectron, provided they adhere to the same DO-41 footprint and electrical limits. Verify pinout compatibility and thermal resistance values when swapping brands to ensure equivalent heat dissipation performance.
