GBU6G-E3/45

Overview

The GBU6G-E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor. It utilizes the GBU surface-mount package and features glass-passivated junctions for enhanced stability. The device supports a peak repetitive reverse voltage of 600 V and an average forward rectified current of 6 A. It exhibits a maximum non-repetitive peak forward surge current of 150 A at 8.3 ms. The component operates within a temperature range of -55°C to +150°C, with a typical forward voltage drop of 1.1 V at rated current.

Feature Summary

• Glass-passivated junction technology ensures reliable operation under varying thermal conditions.
• Surface-mount GBU package design facilitates automated assembly and compact circuit board layouts.

Applications

• General-purpose AC-to-DC power supply conversion circuits
• Battery charging systems requiring moderate current handling
• Industrial control equipment power stages

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm pinout orientation and electrical ratings. Ensure the ordering code matches the required voltage and current specifications for the target application. Cross-reference datasheets for thermal management requirements during high-load operations.

Selection Notes

Select this component when a 600 V rating and 6 A continuous current capacity are required in a surface-mount form factor. Compare thermal resistance values against available heatsinking options. Verify that the package dimensions fit the designated PCB footprint without interference from adjacent components.

Part Context

This part belongs to the GBU series of bridge rectifiers, which are designed for general-purpose applications. The series offers various voltage and current combinations within the same mechanical envelope, allowing for standardized PCB designs across different power requirements.

Replacement Considerations

Direct replacements must match the 600 V reverse voltage, 6 A forward current, and GBU package outline. Verify compatibility with existing thermal constraints and mounting hole positions before substitution.
