KBPC2502W-G

Overview

The KBPC2502W-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for high-current applications. It features a maximum average forward rectified current of 25 A and a peak repetitive reverse voltage of 200 V. The device utilizes the KBPC-W package, which supports screw mounting for secure installation in power electronics systems. Key electrical parameters include a maximum non-repetitive peak surge current of 400 A at 8.3 ms and a maximum DC blocking current of 10 µA at the rated reverse voltage. The component operates within a junction temperature range of -55°C to +150°C and complies with RoHS standards.

Feature Summary

• High thermal stability enabled by epoxy molding compound rated UL94-V0 for flame retardancy
• Robust mechanical construction with isolated case connection suitable for heatsink mounting
• Low forward voltage drop characteristics optimized for efficiency in power conversion circuits

Applications

• AC-DC power supply units requiring high current handling
• Battery charging circuits for industrial equipment
• Inverter free-wheeling diode applications in low voltage systems

Procurement Notes

Verify compliance with specific environmental directives such as RoHS and REACH requirements before integration. Confirm that the ordering suffix matches the desired packaging configuration, as variations may exist between bulk and tray formats. Ensure the supplier provides valid datasheets confirming the electrical ratings align with system design constraints.

Selection Notes

Select this component when a 25 A continuous current rating and 200 V reverse voltage are required in a compact screw-mountable form factor. Evaluate thermal management needs based on the specified junction temperature limits and ensure the PCB or chassis layout accommodates the KBPC-W package dimensions. Compare forward voltage specifications against alternative models to optimize system efficiency.

Part Context

This part belongs to the KBPC series of bridge rectifiers from Comchip Technology, which offers various voltage and current combinations. The KBPC-W variant specifically denotes the wide-body package style designed for enhanced thermal performance and mechanical durability compared to standard plastic encapsulated bridges.

Replacement Considerations

Direct substitutes include other 25 A, 200 V bridge rectifiers in the KBPC-W package such as the GBPC2502W. Verify pinout compatibility and thermal resistance values when cross-referencing with competitors' offerings.
