1N5407G

Overview

The 1N5407G is a silicon rectifier diode manufactured by SMC Diode Solutions, designed for general-purpose applications. It features a maximum average forward rectified current of 3A and a maximum repetitive peak reverse voltage of 800V. The device utilizes a DO-201AD axial through-hole package with an isolated case configuration. Electrical characteristics include a maximum non-repetitive peak forward surge current capability and a junction temperature range spanning from -65°C to 150°C. The component complies with RoHS3 standards and is classified under EAR99.

Feature Summary

• Glass passivated chip junction construction ensures high reliability and low leakage current performance.
• High current capability combined with low forward voltage drop for efficient power conversion.
• Robust surge current handling capacity suitable for demanding circuit conditions.

Applications

• General-purpose rectification in AC/DC power supply circuits
• Bridge rectifier configurations for voltage conversion
• Polarity protection in DC electronic systems

Procurement Notes

Verify the manufacturer designation explicitly as SMC Diode Solutions when sourcing, as the 1N5407G part number is widely produced by multiple semiconductor vendors. Confirm that the specific procurement lot includes the required environmental compliance certifications, such as RoHS3 and halogen-free status, if mandated by your assembly specifications. Cross-reference the datasheet revision to ensure parameter consistency.

Selection Notes

Select this component when a standard silicon rectifier with 800V blocking capability and 3A continuous current rating is required in a through-hole format. Ensure the application does not exceed the specified maximum junction temperature of 150°C or the thermal limits defined in the official datasheet. Consider the DO-201AD package dimensions for PCB layout compatibility and verify that the reverse recovery time meets the frequency requirements of the target circuit.

Part Context

This component belongs to the 1N540x series of glass-passivated silicon rectifiers, which are industry-standard devices for medium-power applications. The 'G' suffix typically denotes specific packaging or environmental compliance attributes within the manufacturer's lineup. It serves as a direct functional replacement for other manufacturers' 1N5407 equivalents, maintaining identical electrical ratings and mechanical footprint for seamless integration into existing designs.

Replacement Considerations

Direct substitutes include equivalent parts from other manufacturers offering 3A, 800V specifications in the DO-201AD package, such as those from Vishay or Taiwan Semiconductor. Verify that any alternative maintains the same pinout, thermal characteristics, and regulatory compliance status before implementation.
