GBPC5004W-G

Overview

The GBPC5004W-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current applications. It features an average forward current of 50 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes a screw mount installation style with solder pin termination, housed in the GBPC-W-4 package. Key electrical characteristics include a forward voltage of 1.1 V at rated current and a surge current capability of 450 A. It operates within a temperature range of -55°C to +150°C and exhibits a low reverse leakage current of 10 µA.

Feature Summary

• High current handling capability suitable for demanding power conversion circuits
• Robust thermal performance allowing operation up to 150°C junction temperature
• Screw mount configuration ensures secure mechanical attachment to heat sinks

Applications

• Industrial power supply units requiring reliable AC-to-DC conversion
• Motor drive systems utilizing high-current rectification stages
• Battery charging equipment operating under variable load conditions

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status through official manufacturer documentation before procurement. Confirm that the GBPC-W-4 package dimensions align with the designated PCB footprint or chassis mounting holes. Ensure the selected component meets the required thermal dissipation specifications for the intended application environment.

Selection Notes

Select this component when a 50 A continuous current rating and 400 V blocking voltage are required. Compare the 1.1 V forward voltage drop against alternative packages to evaluate conduction losses. Verify that the screw mount terminals match the available hardware constraints and that the thermal resistance allows for adequate heat sinking in the final assembly design.

Part Context

This part belongs to the GBPC series of general-purpose bridge rectifiers from Comchip Technology. The 'W' designation typically denotes a specific lead form or package variation optimized for screw mounting. It serves as a higher current alternative to lower-rated bridge rectifiers in the same family, providing a standardized solution for industrial power electronics.

Replacement Considerations

Direct substitutes must maintain the 50 A current rating and 400 V reverse voltage. Compatible alternatives include other manufacturers' GBPC-style bridge rectifiers with identical pinouts and thermal characteristics. Verify that any replacement part supports the same screw mount configuration and meets the required operating temperature range.
