KBU3501-G

Overview

The KBU3501-G is a bridge rectifier manufactured by Comchip Technology, designed for general-purpose power supply applications. It features a single-phase configuration with a maximum average forward rectified current of 3.0 Amperes at a case temperature of 75°C. The device supports a repetitive peak reverse voltage and DC blocking voltage of 1000 Volts. It utilizes a molded plastic epoxy package that meets UL flammability classification 94V-0. The component operates within a junction temperature range of -55°C to +150°C and exhibits a low forward voltage drop of 1.1 Volts at full load.

Feature Summary

• High surge current capability for robust transient protection
• Low forward voltage drop to minimize power dissipation
• Molded plastic package ensuring mechanical stability

Applications

• General-purpose AC to DC conversion in power supplies
• Battery chargers requiring high reliability
• Adapters and inverters for consumer electronics

Procurement Notes

Verify the specific suffix and marking code on the physical component to ensure it matches the KBU3501-G designation exactly. Confirm the manufacturer is Comchip Technology, as similar part numbers exist across different vendors. Check for any recent lifecycle notifications regarding obsolescence or last-time buy status before finalizing procurement plans.

Selection Notes

Select this component when a 3A current rating and 1000V reverse voltage are required in a compact bridge rectifier form factor. Ensure the application's thermal management can handle the power dissipation associated with the specified forward voltage drop at the expected operating ambient temperature.

Part Context

This component belongs to the KBU series of bridge rectifiers from Comchip Technology. The series is characterized by its use in standard power supply circuits where moderate current handling and high voltage isolation are necessary. It serves as a fundamental building block for converting alternating current to direct current in various electronic devices.

Replacement Considerations

Direct replacements must match the 3.0A current rating, 1000V voltage rating, and KBU package outline. Verify pinout compatibility and thermal characteristics before substituting with parts from other manufacturers.
