Product details

TO-220FP full-pack — one fewer assembly step

The TO-220FP (full-pack) package is a fully molded through-hole case with the backside tab electrically isolated from the drain. For a production line that already handles standard TO-220 parts, the FP variant cuts one assembly operation and removes the risk of a cracked insulator. The mounting hole pattern is the same as a standard TO-220, so existing heatsink layouts work without modification.

Gate drive and switching — plan a 10 V rail

Gate threshold is 4.5 V at 100 µA; the specified drive voltage for rated on-resistance is 10 V. Total gate charge is 41 nC at 10 V. Input capacitance is 1145 pF at 25 V drain.

For BOM planning, the base product number is STP9NK65, and the ZFP suffix identifies the TO-220FP full-pack variant.
