Procurement Notes

Verify the specific part number suffix against official documentation to confirm packaging type and compliance status. The provided datasheet indicates that ordering suffixes define packing codes such as Tape and Reel or Tube, and version codes indicating RoHS compliance. Ensure the component matches the required mechanical data and terminal specifications for your assembly process.

Selection Notes

Select this component when designing circuits requiring a 30-volt blocking voltage and 40-ampere continuous current handling in a TO-247AD package. Consider the 0.70-volt forward voltage drop at 20 amperes for thermal management calculations. Verify derating requirements for capacitive loads, which mandate a 20% current reduction, and ensure the operating environment stays within the specified junction temperature limits.
