KBPC50005-G

Overview

The KBPC50005-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current applications. It features an average forward current rating of 50 A and a repetitive peak reverse voltage of 50 V. The device utilizes a glass-passivated chip junction for reliability and operates within a temperature range of -55°C to +150°C. Key electrical parameters include a maximum forward voltage drop of 1.1 V at 25 A and a non-repetitive peak forward surge current capability of 500 A. The component is housed in the KBPC-W-4 package with screw mount installation.

Feature Summary

• Glass passivated chip junction provides stability and protection against voltage transients.
• Electrically isolated metal case facilitates efficient heat dissipation for thermal management.
• High surge current capacity supports robust performance during transient load conditions.

Applications

• General purpose power supply circuits requiring high current rectification.
• Battery charging systems operating at low voltage levels.
• DC power distribution units.

Procurement Notes

Verify the specific suffix configuration when ordering, as variations such as W-G may indicate different packaging or lead times compared to the base model. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Selection Notes

Select this component for designs requiring a 50 A continuous current rating with a 50 V reverse voltage block. Compare the 1.1 V forward voltage drop against system efficiency requirements. Verify that the PCB layout accommodates the KBPC-W-4 footprint and allows for adequate screw mounting clearance. Consider thermal resistance characteristics when designing heatsinking solutions for continuous operation.

Part Context

This part belongs to the KBPC series of glass-passivated bridge rectifiers from Comchip Technology. The series offers various current ratings and voltage options, typically ranging from 15 A to 50 A and voltages up to 1000 V. The KBPC50005-G specifically addresses the lower voltage, high current segment of this family, sharing mechanical dimensions with other variants in the KBPC-W line.

Replacement Considerations

Compatible alternatives include the KBPC50005W-G, which shares identical electrical specifications but may differ in packaging details. Other manufacturers offer equivalent 50 A, 50 V bridge rectifiers in the KBPC-W form factor; verify pinout compatibility and thermal performance metrics before substitution.
