Procurement Notes
Verify the specific datasheet version for the AES2EF-HF to confirm the 300V rating, as manufacturer listings may vary. Ensure the ordering suffix matches the required packaging format. Confirm RoHS compliance status directly with the supplier documentation before integration into production lines.
Selection Notes
Select this component when a compact SMAF footprint is required for automotive applications needing 300V blocking capability. Compare thermal resistance characteristics against alternative packages if board space allows. Validate that the 2A continuous current rating meets the specific circuit load requirements without excessive derating.
Part Context
This part belongs to Comchip Technology's AES series of automotive Schottky diodes. The series provides various voltage ratings tailored for automotive environments. The SMAF package offers a small outline compared to standard DO-214AC equivalents while maintaining similar current handling capabilities for space-constrained designs.
Replacement Considerations
Check for direct substitutes with identical SMAF-2 packaging and 300V/2A ratings. Verify pinout compatibility and thermal performance metrics before substitution.
