S2MHE3_A/H

Single Diodes Overview

The S2MHE3_A/H is a single standard recovery rectifier manufactured by Vishay Semiconductors, housed in the SMB surface-mount package. It supports a maximum average forward rectified current of 1.5 A and withstands a repetitive peak reverse voltage of 1000 V. The device features a low forward voltage drop of 1.15 V at rated current and a maximum non-repetitive surge current capability of 50 A. Reverse leakage current is specified at 1 uA. It operates within a junction temperature range of -55 °C to +150 °C and meets AEC-Q101 automotive qualification standards.

Single Diodes Feature Summary

• Glass passivated chip construction for enhanced environmental stability and reliability under harsh conditions
• Automotive-grade qualification compliant with AEC-Q101 standards for rigorous reliability requirements
• Utilizes high-temperature soldering capabilities suitable for various surface-mount assembly processes

Single Diodes Applications

• General-purpose rectification in industrial power supply circuits
• DC-to-DC converter stages requiring high-voltage isolation
• Automotive electronics systems demanding AEC-Q101 compliance

Single Diodes Procurement Notes

Verify the specific suffix designation upon ordering, as variations may exist between reel and cut-tape packaging formats. Confirm that the procurement channel provides original manufacturer documentation to ensure authenticity. Cross-reference the full part number with official Vishay databases to validate current production status and compliance certifications before finalizing purchase orders.

Single Diodes Selection Notes

Select this component when designing circuits requiring 1000 V blocking capability in a compact SMB footprint. It serves as a suitable replacement for through-hole equivalents where space constraints necessitate surface-mount technology. Ensure thermal management strategies account for the 1.5 A continuous current rating and the specified forward voltage characteristics during conduction phases.

Single Diodes Part Context

This device belongs to the S2x series of glass-passivated fast recovery rectifiers from Vishay. The series is engineered for general-purpose applications in both industrial and automotive environments. The SMB package offers a balance between current handling capacity and board space efficiency compared to smaller signal diode packages.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay SMB-packaged 1000 V rectifiers such as the S2MH or S2MBHE3 variants, provided they match the 1.5 A current rating and package dimensions. Verify pinout compatibility and thermal performance specifications when evaluating alternative manufacturers' offerings.
