Procurement Notes
Verify the specific ordering code suffix to confirm compliance requirements. The base part number indicates RoHS-compliant commercial grade availability. Ensure the selected variant matches the required halogen-free status or automotive qualification level if applicable to the design specifications.
Selection Notes
Select this component for designs requiring fast switching speeds and low conduction losses. The D2PAK package facilitates efficient thermal management through direct heatsink mounting. Verify that the operating junction temperature remains within the specified -65 to +150 °C range during application.
Part Context
This device belongs to the BYW29/BYWB29 series of ultrafast rectifiers from Vishay. The series offers various voltage ratings ranging from 50 V to 200 V while maintaining consistent current handling capabilities. The product line is designed for robust performance in demanding power electronics environments.
Replacement Considerations
Direct substitutes within the same series include BYWB29-50, BYWB29-100, and BYWB29-200, which share identical package and current ratings but differ in reverse voltage blocking capability.
