KBPC3504WP

Overview

The KBPC3504WP is a single-phase silicon bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 35 A and a repetitive peak reverse voltage (VRRM) of 400 V. The device utilizes wire terminals for through-hole mounting and incorporates an isolated aluminum baseplate within its plastic case. Key electrical parameters include a maximum forward voltage (VF) of less than 1.1 V, a peak forward surge current (IFSM) of 375 A at 50 Hz, and a typical reverse recovery time (trr) of approximately 1500 ns. The component operates within a temperature range from -50°C to +150°C.

Feature Summary

• Four diodes integrated in a bridge configuration with UL recognition under File E175067
• Plastic housing constructed with an isolated aluminum baseplate for thermal management
• Compliant with RoHS directives (exemption 7a-I), REACH regulations, and conflict mineral standards

Applications

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

Procurement Notes

Verify the specific ordering suffix WP to confirm wire terminal availability, as FP variants utilize fast-on connectors. Confirm compliance requirements such as RoHS exemption status or AEC-Q101 qualification if applicable to the project. Ensure the procurement documentation matches the exact part number KBPC3504WP to avoid confusion with screw-mount or different voltage rating alternatives within the same series.

Selection Notes

Select this component when a 400 V blocking voltage and 35 A continuous current are required for single-phase applications. The wire terminal design facilitates standard through-hole PCB assembly. Consider the thermal resistance characteristics and derating curves if operating near the maximum junction temperature limit of 150°C. Verify that the surge current capability meets the circuit's inrush requirements.

Part Context

This component belongs to the KBPC3500FP|WP series, which covers a wide voltage range from 100 V to 1600 V while maintaining a consistent 35 A current rating. The KBPC3504WP specifically addresses the 400 V market segment. The series is designed for commercial and industrial applications, offering a standardized footprint and mechanical data across different voltage ratings within the family.

Replacement Considerations

Direct substitutes within the same manufacturer series include KBPC3502WP (200 V) and KBPC3506WP (600 V). Cross-manufacturer equivalents must be verified against the 35 A current, 400 V voltage, and wire terminal specifications.
