Single FETs, MOSFETs Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as variations exist between tape-and-reel and tube formats. Confirm that the component meets the required automotive qualification standards for your specific application environment. Ensure compatibility with the intended PCB footprint for the TO-220AB package during the design phase.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring high current capacity in a through-hole format. Consider the 1.8 mΩ on-resistance for efficiency calculations. Verify thermal management requirements given the 140 W power dissipation rating. Compare against surface-mount alternatives like the IRFR4104 if board space is constrained.

Single FETs, MOSFETs Part Context
