Procurement Notes
Verify the manufacturer designation as Comchip Technology when sourcing this specific part number. Confirm that the suffix -G indicates RoHS compliance status according to official datasheets. Ensure the ordering specification matches the required voltage and current ratings for the intended circuit application.
Selection Notes
Select this component for applications requiring robust single-phase rectification at moderate currents. The 800 V reverse voltage rating provides sufficient margin for standard AC line voltages. Consider the thermal management requirements associated with the 35 A current rating and the screw-mount package style for proper heat dissipation.
Part Context
This model belongs to the KBPC series of bridge rectifiers from Comchip Technology. The series offers various voltage ratings while maintaining a consistent 35 A current capacity. The KBPC3508-G specifically addresses needs for 800 V blocking capability within this standardized form factor.
Replacement Considerations
Cross-reference with other manufacturers offering the KBPC3508 part number, such as Diotec or Vishay. Verify pinout compatibility and physical dimensions before substitution. Ensure equivalent electrical parameters are met to maintain circuit performance integrity.
