Procurement Notes
Verify the specific ordering code suffix against the manufacturer's official documentation to confirm packaging quantity and revision status. Ensure compliance with RoHS directives and material categorization requirements as defined in the datasheet. Confirm that the selected variant meets the necessary AEC-Q101 qualification if intended for automotive applications.
Selection Notes
Select this component for designs requiring high-voltage blocking capabilities up to 1000 V combined with fast switching speeds. The controlled avalanche rating allows for robustness against transient energy events. Consider the thermal resistance characteristics and derating curves when determining heat dissipation requirements for the target application environment.
