GBU608-G

Overview

The GBU608-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting in the GBU-4 package. It features a peak repetitive reverse voltage of 800 V and a continuous forward current rating of 6 A. The component exhibits a maximum forward voltage drop of 1.2 V at rated current and supports a surge overload rating of 175 A. Operating temperatures range from -55°C to +150°C junction temperature, with a low reverse leakage current of 5 µA.

Feature Summary

• High-voltage capability suitable for demanding power supply applications
• Robust surge current handling for transient protection
• Low thermal resistance design for efficient heat dissipation

Applications

• AC-DC power supply circuits
• Battery chargers
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix against official datasheets to confirm electrical parameters, as variations may exist between manufacturers using identical base part numbers. Confirm RoHS compliance status directly with the supplier documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when an 800 V reverse voltage rating is required alongside a 6 A continuous current capacity. Ensure the PCB layout accommodates the GBU-4 package dimensions and that thermal management strategies align with the specified junction temperature limits under expected load conditions.

Part Context

This device belongs to the GBU series of glass-passivated bridge rectifiers, offering high reliability and low forward voltage characteristics. The series is widely utilized in general-purpose rectification applications requiring robust performance in compact through-hole packages.

Replacement Considerations

Direct substitutes include GBU608 from other manufacturers such as SECOS or Taiwan Semiconductor, provided pinout compatibility and electrical ratings match exactly.
