KBPC3516WP

Overview

The Diotec KBPC3516WP is a single-phase diode bridge rectifier rated for a repetitive peak reverse voltage (VRRM) of 1600 V and a maximum rectified output current (IFAV) of 35 A. It features wire terminals and utilizes a plastic case with an isolated aluminum baseplate. Key electrical parameters include a forward voltage drop (VF) below 1.1 V, a peak forward surge current (IFSM) of 300 A at 50 Hz, and a typical reverse recovery time (trr) of approximately 1500 ns. The device supports a maximum junction temperature (Tjmax) of 150°C and has a typical thermal resistance from junction to case of less than 1.5 K/W.

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
• General power supplies
• Commercial and industrial grade equipment

Procurement Notes

Verify the specific ordering suffix to confirm terminal type and compliance status. The standard WP suffix indicates wire terminals. Ensure the procurement documentation matches the required VRRM rating of 1600 V. Confirm that the component meets the necessary commercial or industrial reliability standards for the intended application environment before finalizing orders.

Selection Notes

Select this component when a high-voltage single-phase bridge rectifier is required for mains frequency applications. The 1600 V rating provides significant headroom for standard AC line voltages. Consider the 35 A continuous current capability and the thermal management requirements associated with the isolated aluminum baseplate design for effective heat dissipation in the target enclosure.

Part Context

This part belongs to the KBPC35xx series of single-phase diode bridge rectifiers manufactured by Diotec Semiconductor. The series offers various voltage ratings ranging from 100 V to 1600 V while maintaining a consistent 35 A current rating. The KBPC3516WP specifically represents the highest voltage variant in this standard commercial/industrial lineup with wire termination options.

Replacement Considerations

Direct substitutes must match the 35 A current rating, 1600 V reverse voltage, and KBPC package style. Verify terminal compatibility, as the WP suffix denotes wire leads rather than fast-on tabs. Cross-reference thermal resistance and forward voltage characteristics to ensure equivalent performance in the existing circuit design.
