KBPC2506W-G

Overview

The KBPC2506W-G is a single-phase silicon bridge rectifier manufactured by Comchip Technology. It features an average forward current rating of 25 A and a maximum repetitive peak reverse voltage of 600 V. The device exhibits a typical 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 junction temperature range of -55 °C to +150 °C. The component utilizes a KBPC-W-4 package with screw mount installation and through-hole termination, measuring 28.8 mm in length and width, and 11.23 mm in height.

Feature Summary

• High current handling capability with 25 A average forward rectification
• Robust surge overload protection rated for 300 A peak current
• Integrated metal heat sink design for efficient thermal dissipation
• Electrically isolated base providing 1800 V isolation

Applications

• AC to DC power supply conversion circuits
• Battery charging systems requiring high current rectification
• Industrial motor drive rectifier stages
• General purpose high-current DC power sources

Procurement Notes

Verify the specific suffix W-G against the manufacturer's official datasheet to confirm pinout configuration and mounting hole dimensions. Ensure the procurement documentation explicitly states compliance with RoHS directives as indicated in public listings. Cross-reference the part number with the original equipment manufacturer's approved vendor list to prevent counterfeit components. Confirm that the shipping container type matches the required handling specifications for bulk or tray packaging.

Selection Notes

Select this component when a 25 A continuous current rating and 600 V blocking voltage are required in a screw-mountable package. Compare the 1.1 V forward voltage drop against system efficiency requirements. Verify that the PCB or chassis layout accommodates the KBPC-W-4 footprint dimensions of 28.8 mm x 28.8 mm. Ensure the thermal management strategy can handle the power dissipation associated with the specified forward current and ambient operating temperatures up to 150 °C.

Part Context

This part belongs to the KBPC series of single-phase bridge rectifiers from Comchip Technology. It shares the same physical KBPC-W-4 housing form factor as other variants in the family, such as the KBPC25005W-G and KBPC3504W-G. The primary distinction lies in the voltage and current ratings, with this model specifically optimized for 600 V applications compared to lower or higher voltage siblings.

Replacement Considerations

Publicly documented substitutes include the GBPC2506W from onsemi and generic equivalents like the KBPC2506 from other manufacturers. Verify that replacement parts match the 25 A current rating, 600 V reverse voltage, and identical KBPC-W-4 mechanical footprint. Confirm that the replacement's forward voltage drop and thermal characteristics are compatible with the existing circuit design.
