Single Diodes Procurement Notes

Verify that the specific part number includes the -AQ suffix to ensure compliance with AEC-Q101 automotive standards, as standard commercial grades lack this qualification. Confirm package dimensions match DO-214AC (SMA) requirements during integration. Cross-reference datasheet revision dates to ensure alignment with current manufacturing specifications before finalizing procurement orders.

Single Diodes Selection Notes

Select the ES2J-AQ when applications demand high efficiency combined with robust automotive-grade reliability. The device is suitable for circuits requiring a 2 A continuous current rating with fast switching speeds. Ensure the design accommodates the specified thermal resistance values and verify that the operating voltage does not exceed the rated repetitive peak reverse voltage limits defined in the official documentation.

Single Diodes Part Context

This component belongs to the ES2A through ES2J series of superfast efficient SMD rectifiers produced by Diotec Semiconductor. The series offers various voltage ratings while maintaining consistent mechanical and thermal profiles. The -AQ designation specifically indicates adherence to automotive quality standards, distinguishing it from standard commercial grade variants within the same physical package family.

Single Diodes Replacement Considerations

Direct substitutes must match the 2 A current rating, SMA package, and AEC-Q101 qualification. Verify reverse recovery time and forward voltage specifications against original design constraints before substitution.
