KBU610-G

Overview

The KBU610-G is a bridge rectifier manufactured by Comchip Technology, designed for general-purpose power supply applications. It features a single-phase full-wave configuration with a maximum average forward rectified current of 6 Amperes at a case temperature of 75°C. The device supports a repetitive peak reverse voltage and non-repetitive peak surge forward current rating of 1000 Volts. Constructed with a plastic molded body, it utilizes an epoxy compound rated UL Flammability Classification 94V-0. The component is available in the DO-201AB (DO-203AC) axial leaded package, providing robust mechanical stability for through-hole mounting on printed circuit boards.

Feature Summary

• High surge current capability for handling transient electrical loads
• Epoxy molding compound meets UL flammability standards
• Axial leaded construction for secure PCB mounting

Applications

• General-purpose AC to DC conversion circuits
• Power supply units requiring high reliability
• Battery charging systems

Procurement Notes

Verify the specific manufacturer datasheet for precise thermal derating curves and absolute maximum ratings before integration. Confirm package dimensions against the DO-201AB standard to ensure compatibility with existing footprints. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 6A current rating and 1000V reverse voltage are required for space-constrained axial designs. Ensure the operating junction temperature remains within specified limits to maintain longevity. Compare thermal resistance values against alternative packages if higher heat dissipation is necessary for the specific enclosure design.

Part Context

This component belongs to the KBU series of bridge rectifiers from Comchip Technology, which offers various current and voltage combinations. The KBU610-G specifically addresses mid-range power requirements where axial leads simplify assembly compared to surface-mount alternatives. It serves as a standard solution for industrial and consumer electronics power stages.

Replacement Considerations

Direct substitutes include other 6A, 1000V bridge rectifiers in the DO-201AB package, such as those from Vishay or Littelfuse. Verify pinout orientation and physical dimensions match exactly. Electrical parameters like forward voltage drop and leakage current should be comparable to ensure circuit performance consistency.
