Single Diodes Procurement Notes
Verify the specific ordering suffix matches the required plating finish, as the datasheet indicates that adding the -F suffix denotes a lead-free/RoHS compliant version. Confirm package dimensions and marking details align with design constraints before finalizing procurement orders.
Single Diodes Selection Notes
Select this component for applications requiring a 50V reverse voltage rating and 1.0A continuous current in a compact MELF package. Consider derating current by 20% if used with capacitive loads. Ensure thermal management accommodates the specified terminal temperature limits during operation.
Single Diodes Part Context
This part belongs to the DL4933-DL4937 series of 1.0A surface mount fast recovery rectifiers manufactured by Diodes Incorporated. The series offers varying reverse voltage ratings from 50V to 600V within the same physical MELF package footprint, allowing for design flexibility while maintaining consistent mechanical and thermal characteristics across the product line.
Single Diodes Replacement Considerations
DL4933-13 serves as the non-RoHS equivalent for the DL4933-13-F variant.
Single Diodes FAQ
