Procurement Notes

Verify the specific manufacturer part number against official SMC Diode Solutions documentation to ensure authenticity. Confirm that the received components match the specified GBU package style and pinout configuration. Check datasheet revisions for any updates regarding mechanical dimensions or thermal characteristics prior to integration into final designs.

Selection Notes

Select this component when a robust through-hole solution is required for medium-power rectification tasks. Ensure the application voltage does not exceed the 400 V reverse voltage rating. Consider the thermal management requirements given the 8 A current capacity and the specific thermal resistance characteristics defined in the official datasheet for the GBU package.

Part Context

This component belongs to the GBU series of bridge rectifiers from SMC Diode Solutions. The series offers various voltage ratings while maintaining consistent current handling and package dimensions. The GBU804G specifically addresses applications requiring 400 V isolation with 8 A continuous current flow, fitting into standard through-hole PCB layouts compatible with the 4-ESIP form factor.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 400 V, 8 A single-phase bridge rectifiers in the GBU or similar through-hole packages. Verify that substitute parts meet or exceed the original specifications for reverse voltage, forward current, and surge current ratings.
