S3JB

Single Diodes Overview

The S3JB is a standard recovery rectifier diode manufactured by SMC Diode Solutions. It features an 800 V maximum DC reverse voltage and a 3 A average forward current rating. The device utilizes a glass-passivated die construction for enhanced reliability and is housed in the DO-214AA (SMB) surface-mount package. Key electrical characteristics include a typical forward voltage of 1.2 V at 3 A, a reverse leakage current of 5 µA at 800 V, and a junction temperature range from -65°C to 150°C.

Single Diodes Feature Summary

• Glass-passivated die construction ensures high reliability and stability under varying thermal conditions.
• Low forward voltage drop contributes to improved system efficiency during conduction.
• High surge overload capability supports robust performance against transient current events.

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Freewheeling diode applications in switching converters
• Reverse battery protection mechanisms

Single Diodes Procurement Notes

Verify the manufacturer part number S3JB specifically against official SMC Diode Solutions documentation to confirm technical specifications. Ensure compliance with RoHS directives and REACH regulations as stated in the product datasheet. Confirm the package type matches the required DO-214AA footprint for your design.

Single Diodes Selection Notes

Select this component when a surface-mount solution is required for 800 V blocking voltage applications. The DO-214AA package offers a compact form factor suitable for automated assembly processes. Consider the standard recovery speed and thermal characteristics relative to the specific circuit requirements.

Single Diodes Part Context

This component belongs to the S3K series of surface mount rectifiers from SMC Diode Solutions. The series provides various voltage ratings within the same SMB package outline, allowing for design flexibility while maintaining consistent mechanical dimensions and mounting characteristics across different voltage classes.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering 3 A, 800 V rectifiers in the DO-214AA package. Verify that any substitute part meets or exceeds the original forward voltage, reverse leakage, and thermal resistance specifications.
