GBPC5008-G

Overview

The GBPC5008-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current power conversion applications. It features a silicon GPP construction housed in the GBPC-W-4 package with screw mount terminals. The device supports a continuous forward current of 50 A and withstands a repetitive peak reverse voltage of 800 V. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current and a non-repetitive peak surge current capacity of 450 A. The component operates within a temperature range of -55°C to +150°C and exhibits a low reverse leakage current of 10 µA.

Feature Summary

• Robust mechanical design utilizing screw mount terminals for secure PCB or chassis attachment.
• High thermal stability enabling reliable operation across an extended industrial temperature range.
• Efficient power conversion capability supported by a low forward voltage drop characteristic.

Applications

• Industrial AC-DC power supply units requiring high current handling.
• Battery charging circuits for heavy-duty equipment.
• General-purpose rectification in motor drive systems.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm terminal configuration and compliance status. Ensure that the selected variant matches the required voltage rating and mounting style for the target application. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a 50 A continuous current rating and 800 V blocking voltage are required. The screw mount interface is suitable for applications demanding robust mechanical fixation under vibration. Consider the thermal management requirements associated with the 1.1 V forward voltage drop at full load conditions.

Part Context

This part belongs to the GBPC series of single-phase bridge rectifiers from Comchip Technology. It shares the same 50 A current rating and physical dimensions as variants like the GBPC5006-G and GBPC5010-G, differing primarily in its 800 V peak reverse voltage specification. The series is characterized by silicon planar chip technology and rugged epoxy molding.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the GBPC5006-G (600V) and GBPC5010-G (1000V), provided the voltage margin allows. Other manufacturers offering equivalent 50A screw-mount bridge rectifiers must be evaluated for matching forward voltage and thermal resistance parameters.
