Procurement Notes

Verify the specific suffix designation during procurement, as variations such as 'DG' or 'R' may indicate different packaging formats or reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory updates can alter product classification. Ensure the ordering part number matches the exact electrical and mechanical requirements of the target design to avoid compatibility issues.

Selection Notes

Select this component when designing systems requiring high efficiency and low reverse recovery charge at moderate current levels. The 600 V rating provides adequate margin for standard AC line voltages. Consider the TO-220F-2 package constraints regarding PCB mounting space and thermal pad isolation requirements compared to standard TO-220 variants.
