Typical applications
With its 600 V drain–source rating the STF15NM60ND sits in the high-voltage (offline) class of switching MOSFETs, typically found in primary-side switching in offline SMPS (flyback, forward and quasi-resonant), active PFC boost stages, half-bridge and full-bridge inverters, induction heating and electronic ballasts and BLDC and AC motor drives. The rating leaves usable margin above the ~325 V DC bus obtained by rectifying 230 VAC mains, which is why this class dominates offline power supplies.
Gate drive and switching notes
Keep gate–source voltage within the ±25 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.
Switching behaviour is characterised by a rise time of 20 ns and an output capacitance (Coss) of 65 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the STF15NM60ND
A drop-in substitute for the STF15NM60ND must be the same N-channel type and offer a drain–source rating of at least 600 V, a continuous drain current rating of at least 14 A and an on-resistance no higher than 0.299 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO220FP footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.
Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.
Frequently asked questions
What is the STF15NM60ND?
The STF15NM60ND is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 600 V drain-source and 14 A continuous drain current.
What is the maximum voltage of the STF15NM60ND?
The STF15NM60ND has a maximum drain-source voltage (Vds) of 600 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the STF15NM60ND handle?
It is rated for 14 A of continuous drain current, with power dissipation limited to 30 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the STF15NM60ND?
On-resistance (Rds(on)) is 0.299 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the STF15NM60ND come in?
It is listed in TO220FP. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the STF15NM60ND?
No verified equivalents are listed yet. Choose a part of the same polarity that meets or exceeds every rating above and shares a compatible package and pinout.
