S3MB

Single Diodes Overview

The S3MB is a standard recovery rectifier diode manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 1000 V and an average forward rectified current of 3 A. The device utilizes a glass passivated die construction within a DO-214AB (SMC) surface mount package. Key electrical characteristics include a maximum forward voltage drop of 1.15 V at 2.5 A, a reverse leakage current of 10 µA at 1000 V, and a typical capacitance of 60 pF at 4 V and 1 MHz. It operates within a junction temperature range of -55°C to 150°C.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced environmental stability
• High surge overload rating capability up to 100 A peak
• Low forward voltage drop combined with high current handling
• Ideally suited for automated assembly processes

Single Diodes Applications

• General purpose rectification in power supply circuits
• Bridge rectifier configurations
• DC-to-DC converter output stages

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your design standards. Cross-reference the exact part number with authorized distributors to confirm availability and authenticity before procurement.

Single Diodes Selection Notes

Select this component when a 1000 V blocking voltage and 3 A continuous current are required in a surface mount form factor. The standard recovery speed makes it suitable for lower frequency applications where fast switching is not critical. Compare thermal resistance and package dimensions against existing board layouts to ensure mechanical compatibility.

Single Diodes Part Context

The S3MB belongs to the S3 series of surface mount glass passivated rectifiers produced by SMC Diode Solutions. This series includes variants with different reverse voltage ratings, such as S3A through S3M, sharing common physical dimensions and manufacturing technologies. The SMC package provides a robust solution for high-current applications requiring compact footprints.

Single Diodes Replacement Considerations

Compatible substitutes include Vishay S3M-E3/57T and Diodes Incorporated S3A-13. Verify that alternative parts match the 1000 V reverse voltage, 3 A current rating, and DO-214AB package footprint. Confirm equivalent forward voltage and reverse leakage specifications to maintain circuit performance.
