Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation, as generic suffixes may not accurately reflect the exact electrical or mechanical specifications required for your design. Confirm RoHS compliance status directly through the datasheet or manufacturer certification records prior to finalizing procurement orders. Ensure the package type matches your PCB footprint requirements exactly.

Selection Notes

Select this component when designing circuits that require a 200 V reverse voltage rating combined with a 3.0 A continuous forward current capacity. Consider the DO-214AA (SMB) package dimensions for appropriate board layout planning. Evaluate the thermal resistance and operating temperature limits to ensure adequate heat dissipation under maximum load conditions in your specific application environment.

Part Context

This device belongs to the CDBB series of SMD Schottky Barrier Rectifiers produced by Comchip Technology CO., LTD. The series encompasses various voltage ratings ranging from 150 to 200 Volts while maintaining a consistent 3.0 Ampere forward current capability across the lineup. These components are engineered for modern surface mount assembly processes.

Replacement Considerations

The CDBB3150-HF serves as a related variant within the same product family, sharing identical physical packaging and current ratings but differing in its maximum repetitive peak reverse voltage specification.
