KBU806G T0G

Overview

The KBU806G T0G is a glass passivated single-phase bridge rectifier manufactured by Taiwan Semiconductor. It provides an average forward rectified current of 8 A and supports a maximum repetitive peak reverse voltage of 800 V. The device features a typical instantaneous forward voltage of 1.1 V at 8 A and handles a peak forward surge current of 200 A for 8.3 ms half-sine waves. It operates within a junction temperature range of -55°C to +150°C, with a thermal resistance of 3°C/W (junction-to-case) and 18°C/W (junction-to-ambient). The component utilizes a KBU case package with matte tin-plated leads.

Feature Summary

• Glass passivated chip junction ensures high reliability and stability under varying conditions.
• High case dielectric strength allows safe operation in demanding electrical environments.
• Halogen-free molding compound meets environmental safety standards.
• Matte tin plated leads provide solderability compliant with JESD22-B102 standards.

Applications

• Printed circuit board mounting for general power supply applications
• Industrial equipment requiring robust AC to DC conversion
• Power adapters and chargers

Procurement Notes

Verify the specific ordering suffix T0G to confirm the green halogen-free compound variant. Ensure the procurement documentation references the correct packing code associated with this material specification. Cross-reference the manufacturer's datasheet version H14 for accurate mechanical dimensions and marking diagrams during quality inspection.

Selection Notes

Select this component when an 800 V blocking capability is required alongside an 8 A continuous current rating. Consider the KBU through-hole package for applications needing higher mechanical stability than surface-mount options. Evaluate the thermal resistance values against the system's heatsinking or airflow constraints to ensure the junction temperature remains within the specified operational limits.

Part Context

This part belongs to the KBU80xG series of glass passivated bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, sharing identical current handling and physical packaging characteristics. The '806' designation specifically identifies the 800 V reverse voltage variant within this standardized product family.

Replacement Considerations

Compatible substitutes include other 8 A, 800 V single-phase bridge rectifiers in the KBU package. Verify that replacement parts meet the same 200 A surge current rating and 150°C junction temperature limit. Ensure the alternative component also offers glass passivation and RoHS compliance if environmental regulations apply.
