Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging type. The T4G suffix indicates tape and reel packaging containing 2,500 units. Confirm that the device code marking aligns with the requested part number variant. Ensure compliance with RoHS standards and lead-free requirements as specified in the datasheet. Check for any discontinuation notices regarding this specific series before finalizing procurement plans.

Selection Notes

Select this component for designs requiring fast switching speeds with reduced reverse recovery charge. The matched dual die construction facilitates balanced current sharing when paralleling devices for higher current demands. Evaluate thermal resistance values based on the specific copper pad size used in the PCB layout. Consider the operating case temperature limits when determining heat sinking requirements for continuous operation.
