KBU806G

Overview

The KBU806G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor, designed for through-hole mounting in the KBU package. It features an average forward current of 8A and a maximum repetitive peak reverse voltage of 800V. The device supports a peak non-repetitive forward surge current of 200A at 60Hz. Electrical characteristics include a maximum DC blocking current of 5μA and a typical forward voltage drop of 1V. The component operates within a temperature range from -55°C to +150°C junction temperature.

Feature Summary

• Glass passivated chip elements provide high reliability and resistance to environmental variations.
• High surge current capability ensures robustness against transient overload conditions.
• Low forward voltage drop contributes to improved system efficiency.

Applications

• AC-DC power supply circuits
• Battery chargers
• General-purpose rectification

Procurement Notes

Verify the specific ordering suffix 'K' or 'G' against the manufacturer's official datasheet to confirm packaging type and compliance status. Confirm RoHS directives and halogen-free status with the supplier prior to purchase. Ensure the procurement channel provides traceability documentation matching the Taiwan Semiconductor part number.

Selection Notes

Select this component when an 8A continuous current rating and 800V blocking voltage are required for through-hole applications. Compare the KBU package dimensions against PCB layout constraints. Evaluate thermal management requirements based on the 150°C maximum junction temperature limit under expected load conditions.

Part Context

This part belongs to the KBU8 series of single-phase bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings ranging from 200V to 1000V while maintaining a consistent 8A current capacity and KBU package form factor for standardized board integration.

Replacement Considerations

Direct replacements must match the 8A current, 800V voltage, and KBU package footprint. Verify equivalent electrical parameters such as forward voltage and leakage current. Cross-reference with other manufacturers offering glass-passivated silicon bridge rectifiers in identical mechanical configurations.
