Procurement Notes
Verify the specific part number suffix to confirm compliance with RoHS directives and material categorization standards. Ensure that the ordering quantity aligns with the manufacturer's standard delivery mode specifications. Confirm that the component meets the required thermal resistance ratings for the intended operating environment before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring high voltage blocking capabilities combined with fast switching speeds. Consider the 1600 V reverse voltage rating and 0.5 A continuous current capacity against the expected load requirements. Evaluate the thermal performance characteristics to ensure the junction temperature remains within the specified operating range during operation.
