KBPC3512WP

Overview

The Diotec Semiconductor KBPC3512WP is a single-phase silicon bridge rectifier designed for commercial and industrial applications. It features an average forward current (IFAV) of 35 A at a case temperature of 55°C, with a peak repetitive reverse voltage (VRRM) of 1200 V. The device utilizes wire terminals for through-hole mounting and incorporates a plastic case with an isolated aluminum baseplate. Key electrical characteristics include a maximum forward voltage drop below 1.1 V, a peak non-repetitive surge current of 300 A at 50 Hz, and a typical reverse recovery time of approximately 1500 ns. The component supports a maximum junction temperature of 150°C.

Feature Summary

• Four diodes integrated in a bridge configuration within a plastic housing featuring an isolated aluminum baseplate
• Compliant with RoHS directives and REACH regulations, including conflict minerals standards
• UL recognized under File E175067 for safety certification

Applications

• 50/60 Hz mains rectification
• Commercial power supplies
• Industrial grade equipment

Procurement Notes

Verify the specific ordering suffix to confirm terminal type and compliance status. The standard WP designation indicates wire terminals. Confirm that the requested part matches the required voltage rating of 1200 V and current capacity of 35 A. Ensure the procurement documentation references the correct datasheet version to validate thermal resistance and surge current specifications against the design requirements.

Selection Notes

Select this component when a high-voltage single-phase bridge rectifier is required for mains frequency applications. The 1200 V rating accommodates standard line voltages with significant margin. The wire terminal option facilitates standard PCB assembly processes. Consider the thermal derating curve if the operating case temperature exceeds 55°C, as the continuous current capability decreases accordingly. Verify space constraints for the KBPC package dimensions.

Part Context

This component belongs to the KBPC35xx series of single-phase bridge rectifiers from Diotec Semiconductor. The series offers various voltage ratings ranging from 100 V to 1600 V while maintaining a consistent 35 A current handling capability. The KBPC3512WP specifically addresses applications requiring 1200 V blocking voltage. Other variants in the family share identical mechanical footprints and thermal characteristics, differing primarily in their reverse voltage ratings.

Replacement Considerations

Cross-reference with other manufacturers offering KBPC-style packages with 35 A and 1200 V ratings. Verify pinout compatibility and terminal type (wire vs. fast-on). Ensure equivalent thermal resistance and surge current capabilities are met by potential substitutes.
