GBU804

Overview

The GBU804 is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 8 A. The device utilizes standard recovery technology with a maximum non-repetitive surge peak forward recovery charge of 150 A. It is designed for through-hole mounting in the GBU package, operating within a junction temperature range of -55°C to +175°C.

Feature Summary

• Single-phase full-wave bridge configuration
• High thermal performance junction up to 175°C
• Surge current capability of 150 A

Applications

• AC-DC power supply units
• Battery chargers
• General-purpose rectification in industrial electronics

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact electrical characteristics and mechanical dimensions. Ensure that the procurement documentation explicitly references the GBU804 part number to avoid confusion with similar series components. Cross-reference the RoHS compliance status and packaging options directly with the supplier's current product announcements.

Selection Notes

Select this component for applications requiring robust 400 V blocking capability and 8 A continuous current handling in a through-hole format. Evaluate the thermal management requirements relative to the 175°C junction limit. Confirm that the physical footprint matches the GBU housing specifications. Consider the standard recovery speed suitability for line-frequency operations.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from SMC Diode Solutions. The series provides various voltage and current combinations for general power conversion needs. The GBU804 specifically addresses mid-range current applications requiring high voltage isolation. It serves as a fundamental discrete semiconductor solution for converting alternating current to direct current in compact assemblies.

Replacement Considerations

Direct substitutes include the GBU804G variant from the same manufacturer family. Other compatible replacements may include equivalent 400V 8A bridge rectifiers from different vendors provided they match the GBU pinout and thermal characteristics.
