PB68

Bridge Rectifier Overview

The MCC PB68 is a single-phase glass passivated bridge rectifier rated for 6.0A average forward current and an 800V maximum DC blocking voltage. It features a peak forward surge current rating of 150A (8.3ms, half sine) and a maximum forward voltage drop of 1.10V at 3.0A. The device operates within a junction temperature range of -55°C to +125°C and supports storage temperatures up to 150°C. Reverse leakage current is specified at 10μA at 25°C and 1mA at 100°C.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures stable electrical characteristics and long-term reliability under varying thermal conditions.
• Silver plated copper leads provide low resistance connections and facilitate reliable soldering in various mounting positions.

Bridge Rectifier Applications

• General purpose AC to DC conversion in power supply circuits
• Bridge rectification in industrial control systems
• Battery charging equipment input stages

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance attributes such as halogen-free status or lead finish variations. Ensure the catalog number matches the required voltage rating, as the PB series spans multiple voltage options with identical physical footprints but distinct electrical specifications.

Bridge Rectifier Selection Notes

Select the PB68 specifically when an 800V reverse voltage rating is required for high-voltage AC line applications. Confirm that the 6A continuous current capacity aligns with the load requirements after applying necessary derating factors based on ambient operating temperatures. Verify package compatibility with existing PCB layouts due to the specific lead spacing and mounting hole dimensions.

Bridge Rectifier Part Context

The PB68 belongs to the Micro Commercial Components PB605 through PB610 family of 6 Amp glass passivated rectifiers. This series offers a standardized footprint across multiple voltage ratings, allowing designers to maintain consistent mechanical designs while adjusting for different reverse voltage requirements in single-phase bridge rectifier applications.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 6A current rating, 800V reverse voltage, and PB-6 package dimensions. Equivalent components from other manufacturers should be verified for compatible forward voltage drop and surge current capabilities to ensure circuit performance remains unchanged during substitution.
