Single Diodes Procurement Notes

Verify the specific suffix 'QX' against the official Nexperia datasheet to confirm packaging details and tape-and-reel specifications. Ensure the selected variant matches the required SOD-123F footprint and lead finish for your PCB assembly process. Cross-reference the part number with the manufacturer's latest documentation to validate availability and compliance status before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage, low-current rectification or clamping tasks. The 40V rating and 120mA current capacity define its operational limits. Consider the SOD-123F package dimensions for spatial constraints. Evaluate thermal management requirements based on the expected forward current and ambient operating conditions within the target application circuit.

Single Diodes Part Context

This device belongs to Nexperia's BAS40 series of Schottky barrier diodes, which are engineered for general-purpose switching and rectification. The series emphasizes miniaturization and energy efficiency, making it suitable for portable devices and dense electronic assemblies where space is limited and low power consumption is critical for overall system performance.

Single Diodes Replacement Considerations

Check for direct substitutes such as the BAS40H,115 variant from the same manufacturer family. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure any alternative component meets the same voltage and current ratings to maintain circuit integrity without redesigning the surrounding components.
