Procurement Notes
Verify the specific datasheet version and AEC-Q101 compliance status directly with Comchip Technology or authorized distributors. Confirm that the 1206 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's thermal constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring robust high-voltage rectification in compact spaces. The 800 V rating suits intermediate voltage stages. The leadless 1206 form factor offers superior mechanical stability compared to traditional packages. Verify compatibility with standard reflow soldering profiles specified in the official documentation.
Part Context
This part belongs to the ACURN series of ultra-fast rectifiers. The series includes variants with reverse voltages ranging from 200 V to 1000 V, all sharing the same 1 A forward current capability and 1206 leadless package. This specific model represents the 800 V configuration within the lineup.
Replacement Considerations
Check for other ACURN series variants if voltage ratings differ. Standard 1206 rectifiers may serve as functional substitutes if package compatibility is confirmed. Verify switching speed and reverse leakage current specifications against original requirements.
