GBPC2508-G

Overview

The GBPC2508-G is a single-phase standard bridge rectifier manufactured by Comchip Technology. It features a maximum average forward rectified current of 25 A and a repetitive peak reverse voltage of 800 V. The device utilizes glass passivated die construction to ensure low reverse leakage current and high reliability under varying thermal conditions. Designed for through-hole mounting, it incorporates an integrally molded heatsink within the encapsulation to facilitate efficient heat dissipation. The component meets UL flammability standards with a 94V-0 rating for the plastic material used in its case.

Feature Summary

• Glass passivated die construction provides enhanced stability and low reverse leakage current.
• Integrally molded heatsink design ensures very low thermal resistance for maximum heat dissipation.
• Electrically isolated epoxy case offers high isolation voltage between terminals and the case.

Applications

• General purpose AC to DC power supply circuits
• Battery charging systems requiring high surge current capability
• Industrial equipment power modules

Procurement Notes

Verify the specific manufacturer part number against official Comchip Technology documentation to confirm compliance with RoHS directives and lead-free requirements. Ensure that the ordering suffix matches the exact package and termination specifications required for the target assembly process. Cross-reference datasheet parameters such as thermal resistance and surge current ratings against system design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 25 A current rating and 800 V blocking voltage are required for single-phase rectification. The GBPC2508-G is suitable for applications demanding high surge current handling and robust thermal performance due to its molded heatsink structure. Verify that the operating junction temperature range and forward voltage characteristics align with the efficiency and thermal management goals of the specific power circuit design.

Part Context

This component belongs to the GBPC series of glass passivated single-phase bridge rectifiers. The series encompasses various voltage ratings from 200 V to 1000 V while maintaining a consistent 25 A current capacity. The GBPC2508-G specifically addresses applications requiring 800 V reverse voltage endurance. It shares common mechanical and electrical features with other variants in the family, such as high temperature soldering guarantees and standardized terminal configurations.

Replacement Considerations

Compatible substitutes include the GBPC2508-HF from Comchip Technology and the GBU2508-HF, which offers similar electrical ratings in a different package style. Other manufacturers produce equivalent 25 A, 800 V bridge rectifiers; verify pinout compatibility and thermal resistance values before substitution.
