MB351-BP

Bridge Rectifier Overview

The MB351-BP is a single-phase bridge rectifier diode manufactured by Micro Commercial Components. It features a silicon construction with a maximum average forward rectified current of 35 A and a maximum repetitive peak reverse voltage of 100 V. The device utilizes a metal case package designated as MP-35, which includes four terminals for connection. Key electrical specifications include a non-repetitive peak surge current rating of 400 A. The component is designed for operation within a junction temperature range of -55°C to +125°C.

Bridge Rectifier Feature Summary

• High conductivity metal case construction for efficient thermal dissipation
• Mounting hole compatibility for standard #8 screws to facilitate secure installation
• Capable of supporting any mounting position due to robust mechanical design
• Rated for high surge currents up to 400 amps during transient conditions

Bridge Rectifier Applications

• AC to DC conversion in power supply units
• Battery charging circuits requiring high current handling
• Industrial motor control systems
• General purpose rectification in electronic equipment

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix matches the required voltage rating, as the base series covers multiple voltages. Confirm compliance requirements such as lead content status if RoHS compliance is mandatory for the assembly. Ensure the package type S-MUFM-D4 aligns with the PCB footprint or chassis mounting constraints. Check for UL recognition if safety certification is required for the final product application.

Bridge Rectifier Selection Notes

Select this component when a 35 A continuous current capacity and 100 V reverse voltage are sufficient for the circuit design. Consider the metal case thermal performance for applications where heat dissipation is critical without active cooling. Evaluate the physical dimensions of the MP-35 package against available board space or chassis real estate. Compare surge ratings against potential inrush currents in the specific load scenario.

Bridge Rectifier Part Context

This part belongs to the MB35xx series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings ranging from 50 V to 1000 V, sharing common mechanical and thermal characteristics. The MB351-BP specifically denotes the 100 V variant within this lineup, maintaining consistent current handling and packaging standards across the family.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 35 A current, 100 V reverse voltage, and MP-35 metal case form factor. Generic replacements should be verified for identical pinout configuration and thermal resistance values. Cross-reference with other manufacturers' bridge rectifiers in the same current class, ensuring the replacement supports the required surge current rating.
