Product details

800 V N-channel MOSFET in a fully isolated TO-220FP package

The part targets high-voltage switching applications such as offline AC-DC converters, power factor correction stages, and industrial power supplies where 800 V blocking capability is required.

The total gate charge is 56 nC at 10 V, which gives a reasonable switching speed for a 800 V device in a TO-220FP — the input capacitance measures 1138 pF at 25 V drain-source.

For dual-sourcing, the base product number STP7NK80 covers multiple package variants; the TO-220FP version is the STP7NK80ZFP.

Frequently asked questions

What is the replacement for STP7NK80ZFP?

For a pin-compatible alternative, you would need to compare the full parametric table — 800 V Vdss, 5.2 A Id, 1.8 Ω Rds(on), TO-220FP package — against another vendor's offering. The part is active, so a replacement is not required unless the design needs a different package or performance tier.
