Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm electrical parameters and package type. Ensure the ordered component matches the required AEC-Q101 automotive qualification if intended for vehicle electronics. Cross-reference the part number with authorized distributors to confirm current availability and lead times prior to finalizing procurement orders.

Selection Notes

Select this component when designing circuits that demand rapid switching speeds combined with robust automotive reliability standards. The 3 A current rating and 400 V blocking voltage make it suitable for medium-power conversion stages. Consider the SMC package dimensions for PCB layout constraints and thermal management requirements in dense electronic assemblies.

Part Context

This rectifier belongs to Comchip Technology's KM series of surface-mount diodes, which are engineered for high-speed recovery applications. The series emphasizes low leakage current and high thermal stability, catering to modern electronics that require compact footprints and efficient power handling capabilities in constrained spaces.

Replacement Considerations

Official substitutes include CURC304-HF and CURC304-G, which share identical electrical specifications and package configurations. Verify pinout compatibility and thermal resistance values before implementing any alternative components in existing designs.
