Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with surface-mount assembly processes. Confirm RoHS and REACH compliance status through manufacturer datasheets prior to procurement. Validate that the requested quantity matches the minimum order requirements defined by the supplier.

Single Diodes Selection Notes

Select this component when a 40 V rating and 3 A continuous current capacity are required in a compact SOD-123FL footprint. Consider the low forward voltage drop for thermal management efficiency. Verify that the operating environment aligns with the specified junction temperature limits. Ensure the application does not exceed the 30 A surge current capability during transient conditions.

Single Diodes Part Context

This part belongs to the RBR series of Schottky barrier diodes from ROHM Semiconductor.
