KBPC5002W-G

Overview

The KBPC5002W-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 maximum repetitive peak reverse voltage of 200 V. The device utilizes a glass passivated die construction to ensure low reverse leakage current and high reliability under varying thermal conditions. Electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current and a non-repetitive peak forward surge current capability of 450 A. The component operates within a junction temperature range from -55 °C to +150 °C. It is housed in an electrically isolated epoxy case with internally mounted metal heat sinks to facilitate efficient thermal dissipation.

Feature Summary

• Glass passivated die construction provides enhanced stability against thermal cycling and mechanical shock while maintaining low reverse leakage current.
• Electrically isolated epoxy encapsulation allows for direct mounting to heat sinks without additional insulating hardware, maximizing thermal transfer efficiency.
• Internally mounted metal heat sinks integrated into the bridge structure enable effective heat dissipation for sustained high-current operation.

Applications

• AC-DC power supply circuits requiring robust rectification at 50 A levels
• Battery charging systems utilizing screw-mount topology for secure connections
• Industrial motor drive rectifier stages operating within wide temperature ranges

Procurement Notes

Verify the specific suffix designation during procurement, as the KBPC5002W-G variant may differ in terminal configuration or packaging compared to standard KBPC5002 models. Confirm RoHS compliance status and datasheet revision through official Comchip Technology channels prior to ordering. Ensure that the selected package matches the intended PCB footprint or chassis mounting requirements to avoid integration issues.

Selection Notes

Select this component when a 50 A continuous current rating and 200 V blocking voltage are required in a screw-mountable bridge configuration. Consider the thermal resistance characteristics of the epoxy case with integrated heat sink for system-level cooling design. Compare the 1.1 V forward voltage drop against alternative packages to evaluate conduction losses in the specific application environment.

Part Context

This part belongs to the KBPC5002 series of glass passivated bridge rectifiers from Comchip Technology. It shares the core electrical specifications with other variants in the family but is distinguished by its specific mechanical housing and terminal style. The series is engineered for general-purpose high-power rectification where reliability and thermal performance are critical constraints.

Replacement Considerations

Direct replacements must match the 50 A current rating, 200 V reverse voltage, and screw-mount terminal style. Verify that substitute components offer equivalent thermal resistance and forward voltage characteristics to maintain system performance integrity.
