Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'S' indicates the D3PAK surface-mount package variant distinct from through-hole versions. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to ordering. Ensure the procurement channel provides valid traceability for this Microchip Technology component.

Single FETs, MOSFETs Selection Notes

Select this component when a surface-mount solution is required for 800 V applications. Compare Rds(on) and thermal performance against alternative packages like TO-247 if board space constraints differ. Verify that the 18 A continuous current rating meets the specific load requirements under the intended thermal management conditions.

Single FETs, MOSFETs Part Context

This part belongs to the APT17F80 family of fast recovery epitaxial diode MOSFETs. It shares electrical characteristics with other variants in the series but differs in physical packaging. The 'S' designation specifically identifies the D3PAK form factor, distinguishing it from leaded alternatives within the same voltage and current class.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include other APT17F80 series parts with compatible pinouts, such as the APT17F80B in a TO-247 package, provided mechanical adaptation is feasible. Cross-referencing datasheets for identical Vds, Id, and Rds(on) values is essential for functional equivalence.
