KBPC3514FP

Overview

The Diotec Semiconductor KBPC3514FP 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 1400 V per diode. The device utilizes fast-on terminals and incorporates a plastic case with an isolated aluminum baseplate for efficient thermal management. Key electrical parameters include a maximum forward voltage of 1.1 V, a non-repetitive peak surge current of 375 A at 50 Hz, and a typical reverse recovery time of 1500 ns. The component supports operation up to a maximum junction temperature of 150°C.

Feature Summary

• Four diodes integrated in a bridge configuration within a compact plastic housing
• Isolated aluminum baseplate facilitates effective heat dissipation and mounting
• Fast-on terminals enable rapid assembly using standard 6.3mm connectors
• Compliant with RoHS directives and recognized by UL under File E175067

Applications

• 50/60 Hz mains rectification
• General power supply circuits
• Commercial and industrial grade equipment

Procurement Notes

Verify the specific ordering suffix to confirm terminal type and qualification status. The FP suffix indicates fast-on terminals suitable for screw or solder assembly. Confirm compliance requirements such as REACH and conflict minerals against project specifications. Ensure the selected variant matches the required voltage and current ratings for the intended application environment.

Selection Notes

Select this component when a 1400 V blocking capability and 35 A continuous current are required. The isolated metal base allows direct mounting to heatsinks without additional insulators. Consider the 1.1 V forward voltage drop for efficiency calculations. Verify that the PCB or chassis layout accommodates the specific dimensions of the KBPC package and the spacing required for the fast-on terminals.

Part Context

This part belongs to the KBPC 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 rating. The KBPC3514FP specifically addresses high-voltage AC-to-DC conversion needs in robust industrial environments where reliable thermal performance is critical.

Replacement Considerations

Check for compatible parts within the same KBPC family offering different voltage ratings if system requirements change. Verify mechanical footprint compatibility before substituting with other manufacturers' bridge rectifiers. Ensure equivalent thermal resistance and terminal configurations are maintained to avoid redesigning the cooling solution.
