Procurement Notes
Verify the specific suffix TR indicates reel packaging when sourcing. Confirm the part number matches the exact voltage rating required for the target circuit design. Ensure compatibility with standard SOD-57 footprint dimensions during PCB layout verification.
Selection Notes
Select this component where fast switching speeds are critical to minimize reverse recovery losses. Compare the 200 V reverse voltage rating against peak transient voltages in the application. Consider the SOD-57 package size constraints relative to available board space and thermal dissipation requirements.
Part Context
This part belongs to the BYT series of ultra-fast recovery rectifiers from Vishay. These devices are designed to replace slower standard recovery diodes in modern high-efficiency power electronics. The series offers improved switching performance compared to conventional rectifiers while maintaining robust surge current handling capabilities.
Replacement Considerations
Check datasheets for alternative ultra-fast rectifiers with matching 1.4 A current and 200 V voltage ratings. Verify pinout compatibility if substituting with different manufacturers' SOD-57 packages. Ensure reverse recovery time specifications meet or exceed the original design requirements.
