- Power supply freewheeling diodes
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and qualification status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest datasheet revision to confirm compliance with current environmental directives such as RoHS.
Selection Notes
Select this component for designs requiring robust performance in automotive environments due to its AEC-Q101 qualification. The 2A current rating and 40V voltage limit define the operational boundaries for load switching applications. Consider the thermal management requirements associated with the SMA package when designing the PCB layout for optimal heat dissipation during continuous operation.
Part Context
This device belongs to the Comchip Technology CDBA series of low-profile Schottky barrier rectifiers. These components are engineered for high-speed switching applications where low forward voltage and minimal reverse recovery charge are critical. The series utilizes glass passivation technology to ensure long-term reliability and protection against mechanical stress and environmental factors.
Replacement Considerations
Compatible substitutes include other 2A 40V SMA Schottky diodes such as the SS24 or MBRS240. Verify that alternative parts match the required AEC-Q101 automotive qualification if used in regulated vehicle systems. Confirm pinout compatibility and thermal resistance specifications before implementing any cross-brand replacement.
