Procurement Notes

Verify the component against the official Diodes Incorporated datasheet DS45354 Rev. 5-2 to confirm authenticity. Ensure the ordering suffix matches the required packing quantity and carrier type. Check for AEC-Q101 qualification status if automotive compliance is mandatory. Confirm that the supplier provides traceability documentation consistent with IATF16949 manufacturing standards.

Selection Notes

Select this component when a low-profile SOT23 package is required for space-constrained designs. Choose the BAT64SQ variant specifically for automotive environments due to its AEC-Q101 qualification and PPAP capability. Consider the 40 V reverse voltage rating and 250 mA current capacity to ensure adequate headroom for the target circuit's operating conditions.
