KBPC3514WP

Overview

The Diotec KBPC3514WP is a single-phase diode bridge rectifier rated for a repetitive peak reverse voltage (VRRM) of 1400 V and a maximum alternating input voltage (VVRMS) of 900 V. It provides a continuous forward current (IFAV) of 35 A at a case temperature of 55°C, with a surge current capacity (IFSM) of 375 A at 50 Hz. The device features a typical forward voltage drop below 1.1 V and a reverse recovery time of approximately 1500 ns. It utilizes wire terminals and includes an isolated aluminum baseplate for thermal management.

Feature Summary

• Four diodes integrated in a bridge configuration within a plastic case featuring an isolated aluminum baseplate
• Compliant with RoHS directives and REACH regulations, including conflict minerals requirements
• UL recognized component under file number E175067

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 WP suffix indicates wire terminals. Confirm that the component meets the required automotive or industrial standards if applicable, as standard versions differ from AEC-Q101 qualified variants. Ensure the datasheet version matches the procurement date for accurate mechanical and electrical specifications.

Selection Notes

Select this component when a high-voltage bridge rectifier with wire termination is required. The 1400 V rating suits applications involving significant line voltage spikes. Verify thermal management capabilities, as the 35 A rating depends on maintaining the case temperature at or below 55°C using an adequate heatsink area of 300 cm².

Part Context

This part belongs to the KBPC35xx series of single-phase bridge rectifiers from Diotec Semiconductor. The series covers various voltage ratings from 100 V to 1600 V. The KBPC3514WP specifically addresses high-voltage AC-to-DC conversion needs in commercial and industrial sectors, offering a balance of current handling and voltage blocking capability.

Replacement Considerations

Direct substitutes include other KBPC3514 variants from different manufacturers with identical pinouts and ratings. Ensure replacement parts support wire termination and have comparable thermal resistance values. Verify that any alternative meets the same UL recognition and RoHS compliance standards.
