RB151

Bridge Rectifier Overview

The RB151 is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current of 1.5A and a maximum recurrent peak reverse voltage of 50V. The device has a maximum RMS voltage of 35V and a DC blocking voltage of 50V. Electrical characteristics include a peak forward surge current of 50A, a maximum forward voltage drop of 1.0V at 1.5A, and a reverse leakage current of 10µA at rated voltage. Operating temperature ranges from -55°C to +125°C.

Bridge Rectifier Feature Summary

• Low profile package design suitable for any mounting position
• Silver plated copper leads for reliable connectivity
• Surge overload rating of 50 Amps for high transient tolerance

Bridge Rectifier Applications

• General purpose AC to DC rectification in power supplies
• Bridge rectifier circuits in consumer electronics
• Adapters and chargers with low voltage requirements

Bridge Rectifier Procurement Notes

Verify the part number suffix when ordering. The standard bulk packaging designation is -BP. Halogen-free versions are available by adding the -HF suffix. Ensure procurement from authorized distributors to guarantee genuine components and full traceability as per manufacturer guidelines.

Bridge Rectifier Selection Notes

Select the RB151 for applications requiring a 50V peak reverse voltage rating and 1.5A continuous current. Consider thermal resistance junction to ambient of 40°C/W for heat dissipation planning. Verify that the operating environment stays within the specified -55°C to +125°C range for optimal performance.

Bridge Rectifier Part Context

This component belongs to the RB-15 series of single-phase bridge rectifiers from MCC. The series covers voltage ratings from 50V to 1000V across models RB151 through RB157. All variants share identical physical dimensions and electrical current capabilities, differing only in their reverse voltage breakdown specifications.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same family include RB152 through RB157 if higher voltage ratings are acceptable. Cross-manufacturer replacements must match the 1.5A current, 50V reverse voltage, and RB-15 package footprint. Verify pinout compatibility and thermal characteristics before implementation.

Bridge Rectifier FAQ

What is the maximum forward voltage drop for the RB151?
