KBU8D

Overview

The KBU8D is a single-phase standard bridge rectifier manufactured by onsemi, designed for through-hole mounting in the 4-SIP KBU package. It features an 8 A average forward rectified current rating and a maximum repetitive peak reverse voltage of 200 V. The device supports a wide operating junction temperature range from -55°C to 150°C. With a maximum non-repetitive surge current capability of 300 A at 60 Hz, it provides robust performance for general-purpose power supply applications requiring reliable AC-to-DC conversion.

Feature Summary

• Single-phase bridge rectification topology
• Through-hole mounting configuration
• Wide thermal operating range

Applications

• General-purpose power supplies
• AC-to-DC conversion circuits
• Battery chargers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm part status as obsolete before integration into new designs. Request official datasheets and compliance documentation to ensure material composition and safety standards align with project requirements. Validate package dimensions against PCB footprint specifications prior to procurement.

Selection Notes

Select this component for applications requiring 200 V reverse voltage blocking and 8 A continuous current handling. Ensure the design accommodates the 4-SIP KBU through-hole package constraints. Evaluate thermal management strategies to maintain junction temperatures within the specified -55°C to 150°C operational limits during high-load conditions.

Part Context

This component belongs to the KBU series of bridge rectifiers, characterized by its specific SIP package form factor. It serves as a fundamental building block in low-to-medium power electronic systems where reliable AC input processing is required. The series offers standardized mechanical dimensions for easy integration into existing board layouts.

Replacement Considerations

The product status is listed as Obsolete. Engineers should identify equivalent components from current production lines that match the 200 V, 8 A electrical ratings and 4-SIP KBU mechanical footprint. Verify pinout compatibility and thermal characteristics when sourcing substitutes.
