FCD7N60 MOSFET — Specifications & Equivalents

About the FCD7N60

The FCD7N60 is an N-channel MOSFET with a drain–source voltage (V_DS) rating of 600 V, a continuous drain current (I_D) of 7 A and an on-resistance (R_DS(on)) of 0.6 Ω. It can dissipate up to 83 W. It is available in TO252 and DPAK packages, so confirm the pinout of the exact variant you order.

Typical applications

With its 600 V drain–source rating the FCD7N60 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 FCD7N60

A drop-in substitute for the FCD7N60 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 7 A and an on-resistance no higher than 0.6 Ω if efficiency and heat matter.

Mechanically, check the replacement against the TO252 and DPAK 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 FCD7N60?

The FCD7N60 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 600 V drain-source and 7 A continuous drain current.

What is the maximum voltage of the FCD7N60?

The FCD7N60 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 FCD7N60 handle?

It is rated for 7 A of continuous drain current, with power dissipation limited to 83 W. Real-world capability depends on your heatsinking and ambient temperature.

What is the on-resistance of the FCD7N60?

On-resistance (Rds(on)) is 0.6 Ω. Multiply by the square of your load current to estimate conduction loss.

What package does the FCD7N60 come in?

It is listed in TO252 and DPAK. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the FCD7N60?

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.
