KBPC3508

Overview

The KBPC3508 is a single-phase bridge rectifier manufactured by Good-Ark Semiconductor, designed for high-current applications. It features an average forward current rating of 35 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a standard KBPC package with screw mount installation style. Key electrical parameters include a maximum forward voltage drop of 1.1 V at rated current and a non-repetitive peak surge current capability of 400 A. The component operates within a junction temperature range of -55°C to +150°C, ensuring reliability in demanding power conversion environments.

Feature Summary

• High current handling capability suitable for industrial power supplies
• Robust thermal performance with low forward voltage drop
• Mechanical design optimized for secure screw mounting

Applications

• Industrial power supply units
• DC motor drive circuits
• Battery charging systems

Procurement Notes

Verify the manufacturer part number against official Good-Ark Semiconductor documentation to ensure authenticity. Confirm that the specific revision matches the required electrical specifications. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the procurement channel provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when a 35 A continuous current and 800 V blocking voltage are required in a screw-mountable bridge configuration. Compare the 1.1 V forward voltage drop against system efficiency requirements. Ensure the PCB or chassis layout accommodates the physical dimensions of the KBPC package and allows for adequate heat dissipation given the 400 A surge rating.

Part Context

The KBPC3508 belongs to the KBPC series of single-phase bridge rectifiers from Good-Ark Semiconductor. This series is characterized by its robust construction and suitability for general-purpose rectification tasks. The '35' denotes the 35 A current rating, while '08' indicates the 800 V reverse voltage rating. It is part of a broader family including variants with different voltage ratings such as KBPC3506 and KBPC3510.

Replacement Considerations

Compatible substitutes include the Vishay VS-GBPC3508A, which shares similar electrical characteristics but uses a GBPC package requiring mechanical adaptation. Other potential replacements from manufacturers like Diotec or onsemi should be evaluated based on pin compatibility and thermal resistance values.
