Procurement Notes
Verify the manufacturer origin carefully, as Fairchild Semiconductor has been integrated into ON Semiconductor. Ensure the specific suffix matches your supply chain requirements. Confirm RoHS compliance status with the supplier, as regulatory updates may affect part availability and specifications across different production batches.
Selection Notes
Select this component for designs requiring high voltage blocking capability combined with moderate current handling in a standard through-hole form factor. The 62mΩ on-resistance offers a balance between conduction loss and cost. Ensure the gate driver can provide sufficient voltage to fully enhance the channel for optimal efficiency.
Part Context
This part belongs to the SupreMOS family, which represents advanced MOSFET technology focused on reducing figure-of-merit metrics. The TO-247 package is widely used in industrial and consumer power supplies due to its reliable mounting and heat dissipation characteristics compared to surface-mount alternatives.
Replacement Considerations
Check for equivalents such as FCH47N60F or FCH47N60NF. Verify pinout compatibility and ensure that any substitute maintains the same voltage and current ratings to avoid derating issues in existing PCB layouts.
