The Nexperia BAT54CY,115 is a dual Schottky barrier diode featuring common cathodes and an integrated guard ring for stress protection. Encapsulated in the SOT363-3 (SC-88) surface-mount package, it offers low forward voltage and low capacitance. The device is qualified according to AEC-Q101 standards, making it suitable for automotive applications.
Verify the specific suffix '115' against official Nexperia documentation to confirm reel packaging specifications. Ensure the component meets AEC-Q101 requirements if used in automotive contexts. Cross-reference the SOT363-3 package dimensions with PCB footprint libraries to guarantee mechanical compatibility during assembly.
Select this component when space constraints require a dual Schottky solution in a minimal footprint. The integrated guard ring provides reliability advantages over standard dual diodes. Consider its low capacitance characteristics for high-frequency signal paths where speed and efficiency are critical design parameters.
This part belongs to the BAT54 series of Schottky barrier diodes from Nexperia. It shares functional similarities with other dual Schottky devices but distinguishes itself through the specific SC-88 package geometry and automotive qualification status. It serves as a compact alternative to discrete diode arrangements in dense circuit designs.
Direct substitutes include other dual Schottky diodes in the SOT363 package, such as the BAT54C or BAT54S variants, provided pinout and electrical ratings align. Verify that any replacement maintains the common cathode configuration and AEC-Q101 compliance if automotive use is intended.
