Product details

The STF13N95K3: The 950 V drain-source rating suits offline flyback converters and PFC stages. The TO-220FP full-pack package isolates the tab electrically, allowing direct mounting to a grounded heatsink.

850 mOhm Rds(on) and 51 nC gate charge — the switching trade-off

For a 65–100 kHz flyback or a 50–60 Hz line-frequency switch, the numbers line up well. The input capacitance of 1620 pF at 100 V Vds is modest, keeping the Miller plateau manageable.

Temperature range and package — industrial and beyond

The TO-220FP package limits power dissipation to 40 W at case temperature — enough for the 10 A rating in a well-ventilated enclosure, but you'll want to derate if the case runs hot. The through-hole mounting suits point-to-point wiring on perfboard or automated insertion for medium-volume production.

Frequently asked questions

Can I use STF13N95K3 in a 220V AC application?

Yes. The 950 V drain-source rating provides ample margin for 220 VAC rectified to roughly 310 V DC, plus switching transients. It is well suited for flyback and PFC stages in offline power supplies.

Does STF13N95K3 come in a tape-and-reel package?

The listed package is Tube (through-hole TO-220FP). Tape-and-reel is not indicated for this part; expect tube or bulk shipment for through-hole devices.
