KBP308G

Overview

The KBP308G is a single-phase bridge rectifier manufactured by SMC Diode Solutions, designed for surface-mount applications in the KBP package. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 3 A. The device exhibits a maximum forward voltage drop of 1.2 V at full load current and maintains a low reverse leakage current of 5 µA at rated voltage. Operating within a junction temperature range of -55°C to 150°C, it provides reliable performance for general-purpose power supply circuits requiring compact footprint and robust electrical characteristics.

Feature Summary

• Single-phase bridge rectification architecture integrated into a compact surface-mount form factor
• High voltage blocking capability suitable for demanding AC-to-DC conversion applications
• Thermal stability maintained across extended industrial operating temperature ranges

Applications

• General-purpose AC to DC power supply rectification
• Battery charging circuit input stages
• Adapter and transformer-based power modules

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific packaging quantities against current manufacturer documentation. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Cross-reference datasheet revisions to validate parameter consistency with design specifications.

Selection Notes

Select this component when a surface-mount solution is required for 800 V reverse voltage environments. The 3 A current rating suits moderate power applications where PCB space is constrained. Evaluate thermal management needs based on the KBP package's heat dissipation capabilities relative to the expected ambient temperature and current load profile.

Part Context

This part belongs to the KBP series of bridge rectifiers from SMC Diode Solutions, which offers various voltage and current ratings within the same mechanical outline. The KBP series is engineered for automated assembly processes, providing a standardized footprint that facilitates integration into modern electronics manufacturing lines alongside other SMB and SMA packaged components.

Replacement Considerations

Equivalent parts include the GBU308G for through-hole compatibility or the KBPC308 for alternative sourcing. Verify pinout alignment and thermal pad configuration before substitution to ensure mechanical fit and electrical continuity without redesigning the printed circuit board layout.
