Procurement Notes

Verify that the ordering suffix matches the required packaging quantity and delivery mode. Confirm compliance with RoHS standards and material categorization requirements. Ensure the specific revision code aligns with design specifications. Validate thermal resistance values against the intended mounting conditions on the PCB. Check for AEC-Q101 qualification if automotive grade components are necessary.

Selection Notes

Select this component when high reverse voltage blocking and fast switching speeds are required in a compact surface-mount form factor. Consider the avalanche rating for circuits involving inductive loads or potential voltage spikes. Evaluate thermal management strategies based on the specified junction-to-ambient thermal resistance values under different mounting conditions. Ensure the operating temperature range meets the environmental demands of the target application.
