Product details

STP10NK70ZFP is an N-channel 700 V, 8.6 A MOSFET in a TO-220-3 Full Pack (TO-220FP) through-hole package.

Rds(on) is 850 mOhm max at 4.5 A, 10 V. Gate charge is 90 nC at 10 V. Input capacitance is 2000 pF at 25 V.

Package and thermal routing with the TO-220FP

The TO-220 Full Pack (TO-220FP) is a fully moulded through-hole package with an electrically isolated body. Maximum power dissipation is 35 W at case temperature.

For a production BOM, this means no imminent obsolescence risk and standard lead times through distribution.

Frequently asked questions

What is STP10NK70ZFP used for?

It is a 700 V N-channel MOSFET designed for switching power supplies, offline flyback converters, PFC stages, and high-voltage DC-DC converters where the 700 V rating provides margin for universal AC input (85–265 VAC) designs.

Is STP10NK70ZFP suitable for switching power supplies?

Yes. The 700 V drain-source rating, 8.6 A continuous current, and 850 mOhm Rds(on) make it a suitable choice for the primary-side switch in offline flyback and forward converters up to about 150 W output, with appropriate heatsinking.
