S8G-M3/H

Single Diodes Overview

The Vishay S8G-M3/H is a single glass passivated rectifier diode designed for surface-mount applications. It features an SMPC (DO-214AB) package and supports a maximum average forward rectified current of 8 A with a repetitive peak reverse voltage of 400 V. The device exhibits a typical forward voltage drop of 950 mV at rated current and a maximum non-repetitive surge current capability of 500 A. Reverse leakage current is specified at 10 uA, with a standard recovery time of 3.6 us. It operates within a junction temperature range from -55 C to +150 C.

Single Diodes Feature Summary

• Glass passivation provides mechanical strength and protects against mechanical stresses during handling and operation.
• Surface-mount construction in the SMPC package facilitates automated assembly and compact circuit board layout.
• High thermal performance allows reliable operation under demanding electrical loads.

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Freewheeling diodes in inductive load switching
• DC-DC converter output stages

Single Diodes Procurement Notes

Verify the component marking code matches the official Vishay datasheet specifications for the S8G-M3/H variant. Confirm that the package type corresponds to DO-214AB (SMPC) and that the pinout orientation aligns with your PCB footprint design. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer date code to verify production recency and storage conditions.

Single Diodes Selection Notes

Select this component when a high-current single-phase rectifier is required in a surface-mount form factor. The 400 V rating suits medium-voltage AC-to-DC conversion or DC blocking applications. Consider the 3.6 us recovery time for general frequency operations rather than high-frequency switching scenarios where faster recovery devices are necessary. Evaluate thermal management requirements based on the 8 A continuous current rating.

Single Diodes Part Context

This part belongs to Vishay's family of glass passivated silicon rectifiers. It shares the same physical package and current handling capabilities as other variants in the series but differs in reverse voltage ratings. The S8G-M3/H specifically targets applications requiring 400 V blocking capability, distinguishing it from lower or higher voltage counterparts within the same product line.

Single Diodes Replacement Considerations

Direct replacements must match the 8 A current rating, 400 V reverse voltage, and DO-214AB package. Verify that substitute components maintain similar forward voltage characteristics and recovery times to ensure circuit compatibility without redesign.
