Single Diodes Procurement Notes

Verify the specific suffix QX against official Nexperia documentation to confirm packaging configuration and tape-and-reel specifications. Ensure the component meets AEC-Q101 qualification requirements if intended for automotive use. Cross-reference the SOD323HP package dimensions with mechanical drawings to validate PCB footprint compatibility during the procurement phase.

Single Diodes Selection Notes

Select this component for designs requiring a 40 V reverse voltage rating and 1 A average forward current in a compact surface-mount form factor. The low forward voltage makes it suitable for high-efficiency power conversion circuits. Verify that the thermal performance of the exposed cathode pad meets the system's heat dissipation needs without additional heatsinking.
