KBPC5010WP

Overview

The KBPC5010WP is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for commercial and industrial applications. It features an average forward current (IFAV) of 50 A at a case temperature of 50°C and a repetitive peak reverse voltage (VRRM) of 1000 V. The device utilizes wire terminals and includes an isolated aluminum baseplate within its plastic housing. Key electrical characteristics include a maximum forward voltage (VF) below 1.1 V, a peak forward surge current (IFSM) of 450 A at 60 Hz, and a typical reverse recovery time (trr) of approximately 1500 ns. The thermal resistance from junction to case is less than 1.2 K/W.

Feature Summary

• Features an isolated aluminum baseplate integrated within a plastic case for enhanced thermal management and electrical isolation.
• Equipped with wire terminals (WP version) for through-hole mounting and standard assembly conditions.
• Compliant with RoHS, REACH, and Conflict Minerals regulations for environmental safety.

Applications

• 50/60 Hz mains rectification
• General-purpose power supplies

Procurement Notes

Verify the specific part number against official Diotec documentation to confirm compliance with current manufacturing standards. Ensure that the selected component meets the required thermal dissipation capabilities for the intended application environment. Confirm that the wire terminal configuration aligns with the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 50 A continuous current rating and 1000 V blocking voltage are required in a compact bridge rectifier form factor. Consider the thermal resistance specifications and the necessity for forced cooling if operating near maximum ratings. Evaluate the package dimensions and terminal type to ensure compatibility with existing mechanical constraints and assembly processes.

Part Context

This component belongs to the KBPCxxxxWP series, which encompasses various voltage ratings ranging from 600 V to 1000 V. All variants share identical physical dimensions and thermal characteristics, differing primarily in their peak reverse voltage capabilities. This series provides a standardized solution for high-current rectification needs across multiple industrial power supply designs.

Replacement Considerations

Direct replacements must match the 50 A current rating, 1000 V voltage rating, and KBPC-4 package style. Verify that alternative components offer comparable thermal resistance and reverse recovery times to maintain system performance without redesigning the heat sink or circuit layout.
