Procurement Notes
Verify component authenticity through authorized ROHM distributors or certified partners. Confirm the specific ordering suffix matches the required tape and reel quantity. Check the latest datasheet revision for any updates to absolute maximum ratings or thermal impedance values before finalizing procurement orders.
Selection Notes
Select this component for applications requiring robust general-purpose rectification with moderate current handling capabilities. Ensure the operating ambient temperature allows for proper derating of the 10A average forward current. Verify that the PCB layout accommodates the CPD package dimensions and provides adequate thermal dissipation for the specified junction temperature limits.
Part Context
This component belongs to ROHM's standard Schottky barrier diode lineup, characterized by low forward voltage and high reliability. It is distinct from automotive-grade variants which typically carry specific AEC-Q101 qualifications. The product is designated as not recommended for new designs, indicating it may be phased out or superseded by newer series in future product portfolios.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is marked 'Not Recommended for New Designs', consult official ROHM channels for current equivalent recommendations or updated series replacements suitable for modern designs.
FAQ
What is the thermal resistance from junction to case?
The thermal impedance (junction to case) is specified as a maximum of 6.0 °C/W.
Is this diode qualified for automotive applications?
No, the provided datasheet does not list AEC-Q101 qualification for this specific model; it is intended for general electronic equipment.
What is the maximum reverse recovery time?
The typical reverse recovery time (trr) is approximately 7.40 ns when measured at IF=0.5A and IR=1A.
