UF1010A MOSFET — Specifications & Equivalents
About the UF1010A
The UF1010A is an N-channel MOSFET with a drain–source voltage (VDS) rating of 60 V, a continuous drain current (ID) of 84 A and an on-resistance (RDS(on)) of 0.012 Ω. It can dissipate up to 200 W and is rated to a junction temperature of 150 °C. It is supplied in the TO-220 package.

Typical applications
With its 60 V drain–source rating the UF1010A 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 84 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 0.012 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 78 ns and an output capacitance (Coss) of 690 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the UF1010A
A drop-in substitute for the UF1010A 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 84 A and an on-resistance no higher than 0.012 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO-220 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 UF1010A?
The UF1010A is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 84 A continuous drain current.
What is the maximum voltage of the UF1010A?
The UF1010A 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 UF1010A handle?
It is rated for 84 A of continuous drain current, with power dissipation limited to 200 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the UF1010A?
On-resistance (Rds(on)) is 0.012 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the UF1010A come in?
It is listed in TO-220. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the UF1010A?
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.
