Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm compliance status and packaging configuration. The base part number may be available in tape and reel formats with specified unit counts per reel. Confirm RoHS and halogen-free material declarations against the latest manufacturer documentation before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component for applications requiring low forward voltage drop and fast switching characteristics in a surface mount footprint. Ensure thermal management accounts for the junction-to-ambient resistance when operating near maximum current limits. Validate that the 40 V reverse voltage rating provides sufficient margin for the specific circuit's peak inverse voltage requirements.
