KBPC5008WP

Overview

The Diotec Semiconductor KBPC5008WP is a single-phase bridge rectifier designed for commercial and industrial applications. It features an isolated aluminum baseplate within a plastic case, utilizing wire terminals for connection. The device supports a repetitive peak reverse voltage of 800 V and delivers a maximum rectified output current of 50 A at a case temperature of 50°C. Key electrical parameters include a forward voltage below 1.1 V, a peak forward surge current of 400 A at 50 Hz, and a typical reverse recovery time of 1500 ns. The component operates with a thermal resistance junction-to-case of less than 1.2 K/W and withstands temperatures up to 150°C.

Feature Summary

• Features an isolated aluminum baseplate integrated into a plastic housing for enhanced thermal management and electrical isolation.
• Equipped with wire terminals (WP) for robust mechanical connections and standard through-hole assembly compatibility.
• Compliant with RoHS, REACH, and Conflict Minerals regulations for environmental safety.

Applications

• 50/60 Hz mains rectification
• General power supplies

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm technical specifications before integration. Ensure that the procurement channel provides valid traceability and compliance certificates. Confirm that the ordering suffix corresponds exactly to the required terminal type and packaging format. Cross-reference datasheet revisions to ensure alignment with current manufacturing standards.

Selection Notes

Select this component based on the required 800 V reverse voltage rating and 50 A continuous current capacity. Evaluate the thermal environment to determine if forced cooling is necessary, as the current rating decreases significantly above 50°C case temperature. Verify that the PCB layout accommodates the specific dimensions and screw mounting requirements of the KBPC-4 package.

Part Context

This component belongs to the KBPCxxxxWP series from Diotec Semiconductor, which includes variants ranging from 600 V to 1000 V reverse voltage. The series shares common physical dimensions of 28.6 x 28.6 x 7.3 mm and utilizes a standardized plastic case with an isolated aluminum baseplate. Other available ratings in this family include 600 V, 1000 V, and higher current variants like the KBPC35 series.

Replacement Considerations

Direct substitutes within the same manufacturer's lineup include the KBPC5006WP and KBPC5010WP. These parts share identical physical dimensions and thermal characteristics but differ in their maximum repetitive peak reverse voltage ratings. Ensure the replacement voltage rating meets or exceeds the circuit requirements.
