GBU8G-M3/51

Overview

The GBU8G-M3/51 is a single-phase glass passivated bridge rectifier manufactured by Vishay General Semiconductor. It features an inline package configuration suitable for surface-mount applications. The device is rated for a maximum average forward rectified current of 8 A and a repetitive peak reverse voltage of 400 V. It utilizes glass passivation for junction protection, ensuring high reliability and stability under various operating conditions. The component is designed to meet specific environmental standards, including RoHS compliance.

Feature Summary

• Glass passivated junctions provide enhanced durability and protection against moisture and mechanical stress.
• Inline bridge package design facilitates automated assembly and efficient PCB layout.
• High surge current capability supports robust performance during transient load events.

Applications

• AC-DC power supply units requiring compact rectification solutions.
• Adapters and chargers for consumer electronic devices.
• General-purpose full-wave rectification in industrial control systems.

Procurement Notes

Verify the exact ordering code GBU8G-M3/51 with authorized distributors to ensure correct voltage rating and packaging. Confirm RoHS status and lead times directly with the supplier prior to placement. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a 400 V reverse voltage rating is required alongside an 8 A continuous current capacity. The GBU package offers a balance between thermal performance and board space efficiency. Ensure the application's peak inverse voltage does not exceed the specified limit to maintain long-term reliability.

Part Context

This part belongs to Vishay's GBU series of single-phase bridge rectifiers. The 'M3' suffix indicates lead-free termination and RoHS compliance. The '/51' suffix typically denotes a specific tape-and-reel packaging option, distinguishing it from tube-packaged variants like /45.

Replacement Considerations

Direct replacements must match the 8 A current rating and 400 V reverse voltage. Verify that alternative packages maintain similar thermal resistance and pinout configurations. Consult Vishay documentation for qualified alternate part numbers within the same product family.
