GBJ604

Overview

The GBJ604 is a single-phase bridge rectifier manufactured by SMC Diode Solutions, designed for surface-mount applications in the GBJ package. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 6 A. The device utilizes standard silicon planar technology with a molded epoxy case that meets UL flammability classification 94V-0. Key electrical characteristics include a maximum non-repetitive peak surge forward current capability and a low forward voltage drop to ensure efficient power conversion.

Feature Summary

• Single-phase bridge rectification configuration
• Surface-mount GBJ package design
• Standard silicon planar technology construction

Applications

• General-purpose AC-to-DC power supply circuits
• Battery charging systems
• Industrial control power modules

Procurement Notes

Verify the specific manufacturer part number against official SMC Diode Solutions documentation to confirm pinout compatibility and thermal specifications. Ensure that the procurement source provides valid RoHS compliance certificates and material safety data sheets. Cross-reference the datasheet revision history to confirm that the supplied components match the latest engineering standards and packaging requirements.

Selection Notes

Select this component when a robust surface-mount solution is required for medium-current applications up to 6 A. The 400 V reverse voltage rating makes it suitable for universal input AC lines. Consider the thermal resistance of the GBJ package and the need for adequate PCB copper area for heat dissipation during continuous operation under full load conditions.

Part Context

The GBJ604 belongs to the GBJ series of bridge rectifiers from SMC Diode Solutions, which are widely used in compact electronic designs. This series offers a balance of high current handling and reliable performance in a standardized surface-mount footprint. It serves as a fundamental building block for converting alternating current to direct current in various consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include other 6 A, 400 V single-phase bridge rectifiers in the GBJ package, such as those from Littelfuse or Vishay. Verify that alternative parts match the exact pin configuration, forward voltage characteristics, and thermal performance to ensure seamless integration without redesigning the printed circuit board layout.
