MB258W-BP

Bridge Rectifier Overview

The MB258W-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components. It features a maximum average forward rectified current of 25A and a peak repetitive reverse voltage of 800V. The device operates with a maximum RMS reverse voltage of 560V and supports a maximum non-repetitive surge current of 300A. It utilizes an electrically isolated metal case for efficient heat dissipation, ensuring low reverse leakage current and high efficiency through low power loss characteristics.

Bridge Rectifier Feature Summary

• Electrically isolated metal case design for optimal thermal management
• Low reverse leakage current for improved circuit reliability
• High efficiency operation characterized by low power loss

Bridge Rectifier Applications

• General purpose AC to DC power conversion
• Industrial power supply units

Bridge Rectifier Procurement Notes

Verify the specific suffix BP when ordering to ensure correct lead configuration. Confirm RoHS compliance status as availability may vary by production batch. Check lifecycle status as the component is listed as obsolete in some distributor catalogs; consider alternative sourcing channels or authorized distributors for genuine parts. Validate datasheet revisions before finalizing designs.

Bridge Rectifier Selection Notes

Select this component for applications requiring robust 25A continuous current handling and 800V blocking capability. The metal package construction makes it suitable for environments where effective heat sinking is critical. Ensure the operating junction temperature range aligns with system requirements. Verify that the 300A surge rating exceeds potential inrush currents in the target application to prevent device failure during startup.

Bridge Rectifier Part Context

This part belongs to the MB series of bridge rectifiers from Micro Commercial Components. It is designed for general-purpose rectification tasks in medium-power electronics. The MB-35W package provides a compact solution for through-hole mounting. It serves as a standard replacement for older bridge rectifier designs requiring similar electrical specifications in industrial and consumer equipment.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 25A current rating and 800V reverse voltage. Verify pinout compatibility with the existing PCB footprint. Consider thermal resistance differences if replacing with plastic-packaged alternatives. Ensure the replacement device meets the same surge current requirements to maintain system reliability under transient conditions.
