Procurement Notes
Verify the specific suffix 'R' indicates tape and reel packaging if required for automated assembly. Confirm the manufacturer's datasheet revision date to ensure parameter consistency. Check for RoHS compliance status as per current production standards. Validate pinout compatibility with existing PCB footprints before integration.
Selection Notes
Select this component when high current handling at 350V is required alongside efficient switching. Consider the thermal resistance values for heatsink design. Evaluate gate drive requirements against the specified total gate charge. Ensure voltage derating aligns with system transient spikes.
Part Context
This part belongs to SMC Diode Solutions' NQ series of Super Junction MOSFETs. The series is designed to replace traditional planar MOSFETs in medium-voltage applications. It offers improved figure-of-merit compared to older generation devices. The TO-247-3 package is standard for through-hole mounting in power modules.
Replacement Considerations
Cross-reference with other Super Junction MOSFETs rated for 120A and 350V. Verify pinout compatibility with TO-247-3 packages. Check on-resistance and gate charge specifications for equivalent performance. Confirm availability from alternative manufacturers if supply chain constraints exist.
