KBU2506-G

Overview

The KBU2506-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting in the KBU-4 package. It utilizes silicon technology to provide a maximum average forward rectified current of 25 A and a peak repetitive reverse voltage of 600 V. The component features a maximum forward voltage drop of 1.1 V at rated current and supports a non-repetitive peak surge current of 300 A. It operates within a temperature range of -55 °C to +150 °C junction temperature, with a low reverse leakage current of 10 µA.

Feature Summary

• Robust construction with integrated heatsink capabilities for efficient thermal management
• High surge current handling capacity for reliable operation under transient conditions
• Plastic encapsulation meeting UL flammability classification standards

Applications

• General-purpose power supply circuits
• Battery charging systems
• DC motor drive applications

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Comchip Technology or authorized distributors before procurement. Confirm that the KBU-4 package dimensions align with the target PCB footprint and that the thermal requirements are met by the system design. Ensure ordering suffixes match the required packaging format.

Selection Notes

Select this component when a 25 A current rating and 600 V blocking voltage are required in a through-hole configuration. Compare the 1.1 V forward voltage drop against alternative packages like GBJ or GBPC to evaluate efficiency and thermal dissipation needs. Ensure the application does not exceed the 300 A surge limit during startup or fault conditions.

Part Context

This part belongs to the KBU series of high-current bridge rectifiers from Comchip Technology. It shares similar electrical specifications with other 25 A bridges but differs in physical package size and mounting style compared to the GBJ or GBPC series. The KBU-4 package offers a compact form factor suitable for space-constrained designs requiring screw or through-hole termination.

Replacement Considerations

Direct substitutes include the KBPC3504W-G for higher current ratings or the GBU2506-G for surface-mount compatibility if pinout and thermal performance allow. Verify mechanical fit and thermal resistance characteristics when cross-referencing with Vishay VS-KBU2506 or Panasonic BR2506 equivalents.
