KBU6G/1

Overview

The KBU6G/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage (Vrrm) of 100 V and an average forward rectified current (Io) of 6 A. The device utilizes a KBU package with four pins for through-hole mounting. Key electrical characteristics include a maximum non-repetitive peak forward surge current (Ifsm) of 250 A, a typical peak forward voltage (Vf) of 1 V, and a maximum peak reverse current (Ir) of 5 µA. The junction operating temperature range extends from -50°C to +150°C.

Feature Summary

• Single-phase rectification configuration integrated into a compact KBU package
• High thermal stability supporting operation up to 150°C junction temperature
• Robust surge current handling capability rated at 250 A

Applications

• General-purpose AC to DC power supply conversion
• Low-voltage rectification in industrial control systems
• Battery charging circuits requiring high surge tolerance

Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm exact electrical tolerances and packaging options. Ensure the procurement channel provides valid traceability for automotive or industrial grade requirements if applicable. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints prior to ordering.

Selection Notes

Select this component when a 100 V reverse voltage rating and 6 A continuous current capacity are required for through-hole applications. The KBU package offers mechanical robustness suitable for environments with potential vibration. Evaluate thermal management needs based on the 150°C maximum junction temperature limit and the 1 V forward voltage drop under load conditions.

Part Context

This component belongs to the KBU6 series of bridge rectifiers produced by Vishay General Semiconductor. The series is designed for general-purpose rectification tasks in power electronics. Vishay acquired International Rectifier's discrete semiconductor lines, integrating these products into their broader diode portfolio for industrial and consumer markets.

Replacement Considerations

Compatible substitutes include other 100 V, 6 A single-phase bridge rectifiers in the KBU package, such as the MB6S or KBPC variants from different manufacturers, provided pinout compatibility and thermal ratings match the original design specifications.
