KBU806-G

Overview

The KBU806-G is a single-phase bridge rectifier manufactured by Comchip Technology. It utilizes glass passivation for the cathode junction, ensuring high reliability and resistance to moisture. The device features a maximum average forward rectified current of 8.0 A and a repetitive peak reverse voltage of 600 V. Key electrical parameters include a maximum non-repetitive surge current of 200 amperes and a maximum DC reverse leakage current of 5.0 µA at rated DC blocking voltage. The component operates within a temperature range of -55 °C to +175 °C.

Feature Summary

• Glass passivated cathode junction provides enhanced stability and moisture resistance.
• High surge overload rating supports transient current events up to 200 amperes.
• Designed for efficient printed circuit board mounting applications.

Applications

• General purpose power supply circuits
• Printed circuit board mounted rectification
• AC to DC conversion systems

Procurement Notes

Verify the specific datasheet version from Comchip Technology to confirm exact thermal characteristics and mechanical dimensions. Ensure that the application environment does not exceed the specified maximum junction temperature of 175 °C. Confirm compliance with RoHS directives if required for your manufacturing process. Cross-reference the pinout configuration with your PCB layout to prevent installation errors during assembly.

Selection Notes

Select this component when an 8 A continuous current capacity and 600 V reverse voltage rating are required. The KBU806-G is suitable for designs prioritizing high surge capability and long-term reliability in humid environments due to its glass passivation. Consider the through-hole KBU package constraints regarding board space and thermal dissipation requirements compared to surface-mount alternatives.

Part Context

This part belongs to the KBU series of bridge rectifiers from Comchip Technology. The series is characterized by high current handling capabilities and robust construction for industrial applications. The KBU806-G specifically denotes the 600 V voltage variant within this lineup, sharing common packaging and general structural features with other ratings in the family.

Replacement Considerations

Direct substitutes must match the 8 A current, 600 V voltage, and KBU package form factor. Verify that alternative manufacturers' parts maintain equivalent surge current ratings and thermal performance specifications to ensure circuit integrity without redesign.
