Single Diodes Procurement Notes

Verify that the specific part number includes the -AQ suffix to confirm compliance with the AEC-Q101 automotive qualification standard. Ensure the procurement documentation explicitly references this grade, as it differs from the commercial ES1J variant. Confirm package type matches DO-214AC (SMA) requirements for your PCB layout.

Single Diodes Selection Notes

Select the ES1J-AQ when an application demands both high-speed switching capabilities and adherence to automotive quality standards. This component serves as a direct upgrade to the standard ES1J where AEC-Q101 certification is mandatory. Evaluate the 600V reverse voltage rating against system transients to ensure adequate safety margins during normal operation.
