GBU6B-M3/45

Overview

The GBU6B-M3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes Glass Passivated Chip Junction (GPP) technology and is housed in the GBU-4 inline package. The device supports an average forward rectified current of 6 A and withstands a repetitive peak reverse voltage of 100 V. Key electrical parameters include a maximum RMS diode voltage of 70 V, a non-repetitive peak forward surge current of 200 A at 60 Hz, and a maximum DC blocking voltage of 100 V. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction construction for enhanced environmental stability and reliability under varying conditions.
• High surge current capability designed to withstand transient overloads during power-up or fault events.
• Compliant with international standards including IEC 60130-9 and UL recognition for safety certification.

Applications

• AC-to-DC conversion circuits in general-purpose power supplies
• Battery charging systems requiring robust rectification
• Adapters and converters for consumer electronics

Procurement Notes

Verify the specific suffix /45 against the manufacturer's latest documentation to confirm packaging configuration and compliance status. Confirm RoHS directives and halogen-free status directly from the datasheet before integration. Ensure the ordering part number matches the required lead time and availability constraints for production schedules.

Selection Notes

Select this component when a 6 A current rating and 100 V reverse voltage are required in a standard inline bridge configuration. The GBU-4 package offers a balance of thermal performance and board space efficiency. Consider the operating temperature range and surge current requirements to ensure compatibility with the target circuit's stress levels.

Part Context

This component belongs to Vishay's GBU series of glass passivated bridge rectifiers. The series provides standardized solutions for medium-current applications. The M3 suffix indicates lead-free termination and RoHS compliance, aligning with modern environmental regulations for electronic components.

Replacement Considerations

Direct pin-compatible replacements must maintain the 6 A current rating and 100 V reverse voltage specification. Verify that alternative packages match the GBU-4 footprint and terminal spacing. Ensure thermal characteristics and surge ratings meet or exceed the original design requirements.
