- High voltage blocking capability
Applications
- Automotive power supply circuits
- DC-DC converter output rectification
- Reverse polarity protection in vehicle electronics
Procurement Notes
Verify the exact part number suffix against official documentation, as the input model differs slightly from the verified AES2KF-HF designation. Confirm RoHS compliance status and specific automotive qualification standards required for your application before procurement. Ensure the supplier provides valid traceability documents for automotive components.
Selection Notes
Select this component when high reverse voltage tolerance is required in a small surface-mount package. The 800 V rating exceeds standard automotive system voltages, offering robust transient protection. Consider the thermal performance within the SMAF package for your specific current load requirements.
Part Context
This component belongs to Comchip Technology's automotive diode series, designed specifically for harsh operating environments. The manufacturer emphasizes reliability and consistency for automotive electronics, distinguishing these parts from general-purpose industrial diodes through stricter quality controls and qualification processes.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and electrical specifications with alternative manufacturers if substitution is necessary.
