Single Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm compliance with RoHS standards and AEC-Q101 automotive qualification requirements. Ensure that the procurement specifications match the required package type and delivery mode, as variations exist between commercial grade and qualified automotive grades within the same product family.

Single Diodes Selection Notes

Select this component for designs requiring fast switching speeds and low reverse recovery times in compact surface-mount layouts. Consider the thermal resistance values when determining heat dissipation strategies, particularly regarding operation at elevated ambient temperatures or when mounted on PCBs with limited copper pad areas. Validate the forward voltage drop against system efficiency targets under expected load conditions.

Single Diodes Part Context

This part belongs to the MURS340S/MURS360S series of surface-mount ultrafast plastic rectifiers from Vishay. The series is designed for automated placement and meets MSL level 1 per J-STD-020 standards. The HE3 suffix indicates RoHS compliance and AEC-Q101 qualification, distinguishing it from the standard E3 commercial grade variants.
