GBU4005

Overview

The GBU4005 is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a maximum average forward rectified current of 4.0 A and a peak repetitive reverse voltage of 500 V. The device utilizes the GBU surface-mount package, specifically the 4-ESIP form factor, designed for through-hole mounting on printed circuit boards. Electrical characteristics include a maximum RMS bridge input voltage of 350 V and a non-repetitive peak forward surge current capability of 150 A at 60 Hz for half-cycle sine waves under specified thermal conditions.

Feature Summary

• Utilizes plastic molded construction with an epoxy compound rated UL Flammability Rating 94V-0.
• Features low forward voltage drop to enhance overall system efficiency.
• Equipped with high surge current capability to withstand transient electrical loads.

Applications

• AC-to-DC power supply circuits
• Battery charging systems
• General-purpose rectification in electronic equipment

Procurement Notes

Verify the specific manufacturer datasheet for the GBU4005 to confirm exact electrical tolerances and mechanical dimensions prior to integration. Ensure that the selected component matches the required thermal management specifications for the intended operating environment. Cross-reference official documentation to validate compliance with relevant safety standards and material restrictions applicable to the final assembly.

Selection Notes

Select this component when a 4 A current rating and 500 V reverse voltage are required for AC-to-DC conversion applications. Consider the GBU package size for available board space constraints. Evaluate thermal dissipation requirements based on the expected ambient temperature and forward current load to ensure reliable operation within the specified junction temperature range.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from SMC Diode Solutions. The series offers various voltage ratings while maintaining a consistent 4 A current capacity and standardized footprint. This family is designed for general-purpose rectification tasks requiring robust performance in compact surface-mount configurations.

Replacement Considerations

Compatible substitutes include other 4 A, 500 V bridge rectifiers in the GBU or equivalent package formats. Verify pinout compatibility and thermal characteristics before substitution. Examples may include parts from other manufacturers offering identical electrical ratings in the 4-ESIP housing.
