Product details

100 V N-channel in the TO-220FP — what the specs mean for the BOM

The STMicroelectronics STF110N10F7 is a 100 V N-channel power MOSFET from the DeepGATE™ and STripFET™ VII generation, built for switching applications that need low conduction loss and a fully isolated package. The TO-220FP full-pack variant means the back of the tab is electrically isolated — no insulating pad or washer needed against the heatsink, which simplifies assembly in metal-enclosure equipment.

Obsolete — the sourcing reality

Gate drive and switching considerations

That means a standard 12 V gate drive from a PWM controller or a dedicated gate driver IC will fully enhance the channel.

Frequently asked questions

What is the replacement for STF110N10F7?

The STP110N10F7 is the TO-220 through-hole sibling in the same STripFET VII family — it is pin-compatible but lacks the full-pack isolated tab of the TO-220FP. A parametric search for a 100 V, 7 mOhm N-channel MOSFET in TO-220FP is the practical path for a direct replacement.

What is the difference between STF110N10F7 and STP110N10F7?

The STF110N10F7 comes in the TO-220FP full-pack package, which has an electrically isolated plastic tab — no insulating washer needed against the heatsink. The STP110N10F7 is in a standard TO-220 package where the metal tab is electrically connected to the drain. Both share the same 100 V, 45 A, 7 mOhm die from the STripFET VII family.
