Product details

High-voltage N-channel in a full-pack through-hole package

The STMicroelectronics STFU15N80K5 is an 800 V, 14 A N-channel MOSFET from the MDmesh series, housed in a TO-220FP full-pack package that isolates the tab from the heatsink — no insulating pad needed, which simplifies assembly and improves thermal coupling to the heatsink.

Switching performance and drive requirements

Gate charge is 32 nC at 10 V. Input capacitance is 1100 pF at 100 V Vds, which together with the 32 nC gate charge gives the designer a clear switching-loss budget for the target frequency. The ±30 V maximum gate rating provides margin against overshoot during fast switching edges.

Production status and compliance

The base product number STFU15 identifies this as a TO-220FP variant in the MDmesh family.

Frequently asked questions

What is the closest functional second-source — STFU13N80K5?

The STFU13N80K5 is the next-lower current rating in the same MDmesh K5 family and TO-220FP package — 12 A vs 14 A continuous, with 450 mOhm Rds(on) vs 375 mOhm. It is a direct drop-in for designs that can accept the higher on-resistance and lower current ceiling, but it is not a functional second-source at the full 14 A rating.

Is STFU15N80K5 RoHS compliant?

Yes, the STFU15N80K5 is ROHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive without exemptions.
