Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm packaging details and manufacturing site codes. Ensure the component meets the required AEC-Q101 automotive qualification standards for your target application. Cross-reference the marking code PA followed by a site-specific placeholder to validate authenticity and traceability during the sourcing process.

Selection Notes

Select this component for designs requiring a compact dual Schottky solution in an SOT23 package. The low forward voltage characteristic supports high-efficiency power conversion. Verify that the 40 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements. Consider the thermal resistance characteristics when determining heat dissipation needs on the PCB layout.

Part Context

This device belongs to the PMEG series of low forward voltage Schottky barrier rectifiers manufactured by Nexperia. The series is designed for general-purpose rectification and switching applications where space constraints are critical. The inclusion of the -QR suffix typically denotes a specific tape-and-reel packaging format suitable for automated assembly processes.

Replacement Considerations

Consult official Nexperia substitution guides for verified alternatives. Ensure any replacement maintains the SOT23 footprint and meets the same AEC-Q101 automotive qualification requirements.
