GBU8005

Overview

The GBU8005 is a single-phase bridge rectifier manufactured by SMC Diode Solutions, designed for surface-mount applications. It features an average forward rectified current of 8A and a maximum repetitive peak reverse voltage of 50V. The device utilizes glass passivation for environmental protection and offers a maximum non-repetitive surge current of 300A at 60Hz. Operating characteristics include a maximum RMS reverse voltage of 35V and a peak inverse voltage of 70V. The component is housed in the GBU package, suitable for PCB mounting, with a junction temperature range spanning from -55°C to +150°C.

Feature Summary

• Glass passivated construction ensures reliable operation under harsh environmental conditions
• High surge current capability supports robust performance during transient load events
• Surface-mount GBU package facilitates automated assembly and compact circuit design

Applications

• AC-DC power supply circuits
• Battery charging systems
• General-purpose rectification in low-voltage DC conversion

Procurement Notes

Verify that the specific order matches the manufacturer part number GBU8005 from SMC Diode Solutions. Confirm the package type corresponds to the standard GBU surface-mount configuration. Ensure compliance with RoHS directives if required by the end application. Check datasheet specifications for thermal management requirements relative to the 8A continuous current rating.

Selection Notes

Select this component when a high-current, low-voltage bridge rectifier is required for surface-mount designs. The 50V rating limits suitability to low-voltage AC inputs or secondary side rectification. Consider the 8A current capacity against thermal dissipation constraints in the final enclosure. Compare alternative packages if through-hole mounting is necessary due to space limitations.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers produced by SMC Diode Solutions. The series provides various current and voltage combinations within the same physical footprint. The GBU8005 specifically addresses applications requiring 8A capacity with a 50V blocking voltage, fitting into the broader portfolio of glass-passivated bridge rectifiers.

Replacement Considerations

The GBU8005 serves as a direct substitute for the GBU8005-G. Both parts maintain identical electrical ratings and physical dimensions. Verify pinout compatibility and thermal characteristics when replacing equivalent components from other manufacturers.
