Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and delivery mode. The E3 suffix indicates commercial grade compliance with JESD 201 class 1A whisker testing standards. Confirm that the required thermal management aligns with the specified junction-to-case thermal resistance values provided in the datasheet.
Selection Notes
Select this component when a low-profile surface mount rectifier with fast recovery characteristics is required. Ensure the application voltage does not exceed the 200 V peak repetitive reverse voltage rating. Consider the thermal resistance from junction to air when designing heatsinking solutions for ambient temperature conditions above 25 °C.
Part Context
This part belongs to the BY229(X,B)-200 through BY229(X,B)-800 series of fast switching plastic rectifiers. The series offers various voltage ratings ranging from 200 V to 800 V while maintaining consistent current handling capabilities. The BY229B variant specifically utilizes the TO-263AB package format.
Replacement Considerations
Direct substitutes within the same series include BY229X-200-E3/45 (ITO-220AC package) and BY229-200-E3/45 (TO-220AC package). Verify pinout compatibility and physical mounting dimensions before substituting different package variants.
