• Epoxy case with metal bottom for thermal management
• Halogen-free construction available upon request

Bridge Rectifier Applications

• General-purpose power supply circuits
• Battery charging systems
• Industrial control equipment

Bridge Rectifier Procurement Notes

Verify the specific suffix designation against official MCC documentation to confirm compliance requirements, as suffixes may indicate variations in packaging or material composition such as halogen-free status. Confirm the package type matches the intended PCB footprint, as MP358W-BP variants may differ from standard MB series packages. Ensure the ordering information aligns with the latest datasheet revisions to avoid discrepancies in electrical parameters or mechanical dimensions.

Bridge Rectifier Selection Notes

Select this component when a 35 A continuous current capacity and 800 V blocking voltage are required in a through-hole bridge rectifier format. The MP-50W-4 package provides robust thermal performance for high-current applications. Consider the 1.1 V forward voltage drop for efficiency calculations in low-voltage output designs. Verify that the 400 A surge capability meets the inrush current demands of the target circuit load.

Bridge Rectifier Part Context

The MB358W-BP belongs to the MP358W series of single-phase bridge rectifiers from Micro Commercial Components. This series is designed for general-purpose rectification in power electronics. The device shares functional similarities with other 35 A bridge rectifiers but is distinguished by its specific 800 V rating and MP-50W-4 package style. It serves as a discrete solution for converting alternating current to direct current in medium-power applications.

Bridge Rectifier Replacement Considerations

Publicly confirmed substitute part numbers for the MB358W-BP were not identified in the provided source data. Cross-referencing with other 35 A, 800 V single-phase bridge rectifiers in the MP-50W-4 package is recommended. Verify pinout compatibility and thermal resistance specifications before substituting with components from other manufacturers.
