FCH47N60NF MOSFET — Specifications & Equivalents
About the FCH47N60NF
The FCH47N60NF is an N-channel MOSFET with a drain–source voltage (VDS) rating of 600 V, a continuous drain current (ID) of 28.9 A and an on-resistance (RDS(on)) of 0.065 Ω. It can dissipate up to 368 W and is rated to a junction temperature of 150 °C. It is available in TO247, TO3P and TO3PF packages, so confirm the pinout of the exact variant you order.

Typical applications
With its 600 V drain–source rating the FCH47N60NF 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 ±30 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.
Choosing a replacement for the FCH47N60NF
A drop-in substitute for the FCH47N60NF 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 28.9 A and an on-resistance no higher than 0.065 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO247, TO3P and TO3PF 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 FCH47N60NF?
The FCH47N60NF is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 600 V drain-source and 28.9 A continuous drain current.
What is the maximum voltage of the FCH47N60NF?
The FCH47N60NF 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 FCH47N60NF handle?
It is rated for 28.9 A of continuous drain current, with power dissipation limited to 368 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the FCH47N60NF?
On-resistance (Rds(on)) is 0.065 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the FCH47N60NF come in?
It is listed in TO247, TO3P and TO3PF. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the FCH47N60NF?
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.
