RB155

Bridge Rectifier Overview

The MCC RB155 is a single-phase bridge rectifier rated for 1.5 A average forward current and 600 V maximum recurrent peak reverse voltage. It utilizes the RB-15 through-hole package with silver-plated copper leads. Electrical characteristics include a maximum forward voltage drop of 1.0 V at 1.5 A, a peak forward surge current rating of 50 A, and a maximum DC reverse leakage current of 10 µA at 25°C. The device operates within a junction temperature range of -55°C to +125°C and features a thermal resistance from junction to ambient of 40°C/W.

Bridge Rectifier Feature Summary

• Low profile package design suitable for any mounting position
• Surge overload rating capable of handling 50 Amps
• Silver plated copper leads for reliable connection

Bridge Rectifier Applications

• General purpose AC to DC conversion in resistive or inductive loads
• Power supply circuits operating at 60Hz
• Industrial control systems requiring robust bridge rectification

Bridge Rectifier Procurement Notes

Verify part authenticity by purchasing directly from Micro Commercial Components or authorized distributors to ensure traceability and quality standards. Confirm packaging options, such as bulk quantities, match project requirements. Check for specific suffixes like -BP for bulk packing or -HF for halogen-free variants if environmental compliance is necessary. Ensure storage conditions align with moisture sensitivity level 1 specifications.

Bridge Rectifier Selection Notes

Select the RB155 when a 600V blocking voltage and 1.5A continuous current are required in a through-hole configuration. Consider the RB-15 package dimensions for PCB layout constraints. Evaluate thermal management needs based on the 40°C/W junction-to-ambient resistance. Compare against other voltage ratings in the RB151-RB157 series if system voltage requirements differ.

Bridge Rectifier Part Context

The RB155 belongs to the RB151 through RB157 series of 1.5 Amp single-phase bridge rectifiers manufactured by Micro Commercial Components. This family offers various voltage ratings from 50V to 1000V while maintaining consistent current and package specifications. The RB-15 package provides a standardized footprint for easy integration into existing designs requiring through-hole bridge rectification.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include RB154 (400V) or RB156 (800V) if voltage margins allow. Other manufacturers offering similar 1.5A, 600V bridge rectifiers in RB-15 packages may be considered, but verify pinout compatibility and electrical parameters. Ensure replacement parts meet the same thermal and surge current requirements.
