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 RoHS and halogen-free compliance requirements align with project specifications before finalizing procurement.

Selection Notes

Select this component when a low forward voltage and fast switching speed are critical for the circuit design. The SOT23 package offers a compact footprint suitable for space-constrained layouts. Consider the 40 V reverse voltage rating and 250 mA current capacity to ensure adequate headroom for operational conditions. Verify thermal management needs based on the specified power dissipation limits.

Part Context

This part belongs to the BAT64Q/AQ/CQ/SQ family of surface-mount Schottky barrier diodes. The 'CQ' designation specifically denotes the variant with a 40 V reverse voltage rating. These devices are designed for general-purpose high-speed switching and are suitable for automotive environments due to their robust construction and qualification standards.

Replacement Considerations

BAT64AQ-13-F: Same package but different voltage/current characteristics. BAT64SQ-13-F: Same package but different voltage/current characteristics. Verify pinout compatibility and electrical parameters before substitution.
