Single Diodes Procurement Notes

Verify the specific voltage rating against project requirements, as datasheet listings indicate both 30 V and 40 V variants within this product family. Confirm package type PMDE-2 compatibility with PCB footprint designs. Ensure sourcing channels provide genuine ROHM Semiconductor products to maintain AEC-Q101 compliance and automotive grade integrity.

Single Diodes Selection Notes

Select this component when automotive qualification is mandatory and low forward voltage drop is required for efficiency. Compare reverse leakage current specifications against other 1 A Schottky diodes to ensure minimal power loss. Verify that the PMDE-2 package dimensions fit the available board space and that the 150°C operating temperature meets the environmental constraints of the target application.

Single Diodes Part Context

This part belongs to ROHM's automotive-grade Schottky barrier diode lineup, specifically engineered for high-reliability environments. It complements other series like the RBS and RBR families, offering specialized performance for vehicles where component failure is not an option. The PMDE-2 package provides a compact solution for modern automotive electronics.

Single Diodes Replacement Considerations

Direct substitutes may include other AEC-Q101 qualified 1 A Schottky diodes in similar packages. Verify pinout compatibility and thermal resistance values before substitution. Alternative parts must meet or exceed the 150°C junction temperature rating and 50 uA reverse leakage specification.
