Procurement Notes
Verify the specific part marking against official Diotec Semiconductor documentation to confirm authenticity. Ensure that the component meets the required environmental standards for your application. Cross-reference the datasheet revision date with your procurement records to guarantee access to the most current technical specifications and reliability data before finalizing orders.
Selection Notes
Select this component when a 3 A continuous current rating and 200 V blocking voltage are required. Consider the 1500 ns reverse recovery time for frequency limitations in switching applications. Evaluate thermal management requirements based on the specified thermal resistance values and ambient temperature derating curves provided in the official datasheet.
Part Context
This component belongs to the BY251 through BY255 series of standard recovery rectifier diodes produced by Diotec Semiconductor. These devices share similar structural designs but vary primarily in their peak repetitive reverse voltage ratings. The series provides reliable performance for commercial and industrial grade applications requiring standard switching speeds.
Replacement Considerations
Consult official Diotec Semiconductor documentation for confirmed substitute part numbers within the same product family or equivalent specifications.
