GBU2504-G

Overview

The GBU2504-G is a glass passivated single-phase bridge rectifier manufactured by Comchip Technology. It features an average forward rectified current of 25 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes a GBU package with integrated heatsink capabilities for efficient thermal dissipation. Key electrical characteristics include a low forward voltage drop to enhance efficiency and high surge current capability to withstand transient loads. The component is designed for general-purpose rectification in switching mode power supplies and adapters, operating within a specified junction temperature range.

Feature Summary

• Glass passivated die construction ensures stable performance and reliability under various operating conditions.
• Integrally molded heatsink design provides very low thermal resistance for maximum heat dissipation.
• Low forward voltage drop enhances overall system efficiency during rectification operations.

Applications

• General purpose single phase bridge rectifier circuits
• Switching mode power supply (SMPS) input stages
• AC to DC adapter applications

Procurement Notes

Verify the manufacturer marking on the component body matches Comchip Technology specifications. Confirm the part number suffix -G indicates RoHS compliance as per official datasheets. Check for physical damage to leads and ensure the plastic molding integrity is intact before integration into production lines.

Selection Notes

Select this component when a 25 A current rating and 400 V reverse voltage are required in a surface-mountable bridge configuration. Ensure the application's thermal environment allows for adequate heat sinking due to the integrated heatsink design. Verify that the glass passivation meets the environmental requirements of the target assembly process.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from Comchip Technology. It shares the same mechanical footprint and pinout with other variants in the series that offer different voltage ratings, such as 600 V or 1000 V options, while maintaining the 25 A current capacity.

Replacement Considerations

Compatible substitutes include the GBU2504 from Taiwan Semiconductor and similar 25 A, 400 V glass passivated bridge rectifiers from other manufacturers. Ensure the replacement maintains the same GBU package dimensions and lead spacing for direct board compatibility.
