GBPC50005-G

Overview

The GBPC50005-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for general-purpose power conversion applications. It features a peak forward average rectified current of 50 A and a maximum repetitive peak reverse voltage of 50 V. The device utilizes a standard silicon planar chip design with an epoxy case that meets UL flammability classification 94V-0. Electrical characteristics include a maximum non-repetitive peak surge current capability of 600 A at a specified half-sine wave duration. The component operates within a junction temperature range from -55°C to +150°C and maintains a low forward voltage drop typical for this class of rectifier.

Feature Summary

• High current carrying capacity suitable for demanding power supply circuits
• Robust surge current handling capability for transient protection
• Epoxy case construction compliant with UL 94V-0 flammability standards

Applications

• General purpose full-wave bridge rectification in AC-DC converters
• Power supply units requiring high current output
• Battery charging circuits

Procurement Notes

Verify the specific datasheet version for the GBPC50005-G to confirm exact electrical tolerances and mechanical dimensions prior to integration. Ensure the supplier provides official documentation confirming compliance with RoHS directives and material declarations. Cross-reference the part number against the manufacturer's latest obsolescence notices to guarantee long-term availability and consistency in manufacturing processes.

Selection Notes

Select this component when a 50 A continuous current rating and 50 V reverse voltage blocking capability are required in a screw-mountable package. Compare thermal resistance values against the intended heatsinking strategy to ensure junction temperatures remain within safe operating limits under maximum load conditions. Verify that the physical footprint matches the PCB or chassis mounting holes available in the design.

Part Context

This part belongs to the GBPC series of bridge rectifiers from Comchip Technology, which offers various current and voltage combinations. The GBPC50005-G specifically addresses the need for high-current, low-voltage rectification. It shares the same mechanical housing style as other GBPC variants but differs in internal die configuration to support the 50 A rating. This places it in a niche between lower current surface mount bridges and higher current industrial modules.

Replacement Considerations

Direct replacements must match the 50 A / 50 V specification and the GBPC-4 package outline. Equivalent parts from other manufacturers such as Littelfuse or Vishay should be verified for identical pinout and thermal performance characteristics.
