Procurement Notes

Verify the specific manufacturer designation on the component marking to distinguish between Comchip Technology and other producers using similar part numbers. Confirm RoHS compliance status through official documentation prior to integration. Ensure the procurement channel provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when a 4 A current rating and 100 V reverse voltage are required for through-hole applications. Compare the 1.1 V forward voltage drop against system efficiency requirements. Evaluate the KBL package dimensions against available PCB real estate constraints before finalizing the design.

Part Context

This component belongs to the KBL series of bridge rectifiers, which are widely utilized in general-purpose power applications. The KBL402 variant specifically denotes the 100 V rating within this family. Similar devices include the KBL404 and KBL406, which offer higher voltage ratings while maintaining the same current capacity and physical footprint.

Replacement Considerations

Compatible substitutes include the KBL402G from Taiwan Semiconductor and GeneSiC Semiconductor, provided the pinout and electrical parameters match exactly. Verify that alternative sources maintain the same KBL package dimensions and thermal characteristics to ensure seamless board compatibility.
