1N4004

Single Diodes Overview

The SMC Diode Solutions 1N4004 is a general-purpose silicon rectifier diode designed for AC-to-DC conversion in power supply circuits. It features a maximum average forward rectified current of 1A and a maximum repetitive peak reverse voltage of 400V. The device utilizes a DO-41 axial leaded package with a plastic molding compound rated UL 94V-0 for flammability. Key electrical characteristics include a typical forward voltage drop of 1.1V at 1A and a low reverse leakage current of 5µA at 400V. It offers high forward surge current capability and is guaranteed for high-temperature soldering, making it suitable for various industrial and consumer applications requiring reliable standard recovery performance.

Single Diodes Feature Summary

• Glass passivated junction construction ensures stable operation under varying thermal conditions
• High forward surge current capability provides robustness against transient overloads
• Low reverse leakage current contributes to improved efficiency and reduced heat generation
• Molded plastic case meets UL 94V-0 flammability classification standards

Single Diodes Applications

• AC to DC converter circuits in power supplies
• Bridges in rectifier applications
• Polarity protection circuits
• General purpose rectification in electronic equipment

Single Diodes Procurement Notes

Verify the manufacturer designation explicitly states SMC Diode Solutions, as the 1N4004 part number is widely produced by multiple vendors. Confirm the package type is DO-41 axial leaded and check for specific suffixes that may indicate packaging variations or compliance updates. Ensure the datasheet matches the required electrical parameters, specifically the 400V reverse voltage and 1A current ratings, to avoid substitution errors from other manufacturers.

Single Diodes Selection Notes

Select this component when a standard recovery time is sufficient for line-frequency rectification applications. The 400V rating provides adequate margin for 220V AC systems, while the 1A current capacity suits low-power devices. Consider the DO-41 package for through-hole mounting requirements. For higher speed switching needs, a fast recovery diode would be more appropriate than this standard rectifier type.

Single Diodes Part Context

The 1N4004 belongs to the widely recognized 1N400x series of general-purpose silicon rectifiers. This series is standardized across the semiconductor industry for basic power conversion tasks. While many manufacturers produce compatible parts, specific parameters like reverse leakage and forward voltage can vary slightly between brands. The SMC Diode Solutions version adheres to these standard specifications within the DO-41 form factor.
