KBU6G

Overview

The KBU6G is a single-phase bridge rectifier manufactured by onsemi, designed for through-hole mounting in the GBU-4 package. It features a maximum average forward rectified current of 6 A and a peak repetitive reverse voltage of 600 V. The device exhibits a low forward voltage drop of 1 V at rated current and supports a maximum surge current of 175 A. Operating within a temperature range of -55 °C to +150 °C, it offers a power dissipation capacity of 12 W and minimal reverse leakage current of 5 µA, ensuring reliable performance in general-purpose rectification applications.

Feature Summary

• Robust construction with high thermal stability for demanding environments
• Low forward voltage drop for improved energy efficiency
• High surge current capability for transient protection

Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems
• DC power adapters

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compliance with RoHS directives if required by the target application. Cross-reference manufacturer part numbers directly to avoid substitution errors due to minor nomenclature variations.

Selection Notes

Select this component when a 6 A current rating and 600 V blocking voltage are required in a compact through-hole footprint. Evaluate thermal management requirements based on the 12 W power dissipation limit. Consider the operating temperature range to ensure suitability for the intended environmental conditions.

Part Context

This component belongs to the GBU series of bridge rectifiers from onsemi, known for their reliability in industrial and consumer electronics. The GBU-4 package provides a standardized form factor compatible with various PCB layouts. It serves as a fundamental building block for converting alternating current to direct current in power conversion stages.

Replacement Considerations

Direct substitutes must match the 6 A current rating, 600 V voltage rating, and GBU-4 package type. Verify equivalent forward voltage and reverse leakage specifications to maintain circuit performance.
