Typical applications
With its 60 V drain–source rating the IRFB3006G sits in the mid-range class of switching MOSFETs, typically found in 24 V and 48 V industrial and battery systems, motor drives and H-bridges and load and hot-swap switching.
The 270 A current rating puts it in high-current territory, where conduction loss (I² × RDS(on)) and thermal design usually matter more than switching loss. Budget for adequate copper area and a heatsink.
The low 0.0025 Ω on-resistance keeps conduction loss down, which suits synchronous rectification and continuous high-current paths.
Gate drive and switching notes
Keep gate–source voltage within the ±20 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.
Switching behaviour is characterised by a rise time of 182 ns and an output capacitance (Coss) of 1020 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the IRFB3006G
A drop-in substitute for the IRFB3006G must be the same N-channel type and offer a drain–source rating of at least 60 V, a continuous drain current rating of at least 270 A and an on-resistance no higher than 0.0025 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO220AB 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 IRFB3006G?
The IRFB3006G is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 270 A continuous drain current.
What is the maximum voltage of the IRFB3006G?
The IRFB3006G has a maximum drain-source voltage (Vds) of 60 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the IRFB3006G handle?
It is rated for 270 A of continuous drain current, with power dissipation limited to 375 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the IRFB3006G?
On-resistance (Rds(on)) is 0.0025 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the IRFB3006G come in?
It is listed in TO220AB. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the IRFB3006G?
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.
