25N06 MOSFET — Specifications & Equivalents
About the 25N06
The 25N06 is an N-channel MOSFET with a drain–source voltage (VDS) rating of 60 V, a continuous drain current (ID) of 25 A and an on-resistance (RDS(on)) of 0.048 Ω. It can dissipate up to 90 W and is rated to a junction temperature of 150 °C. It is available in TO-220 and TO-252 packages, so confirm the pinout of the exact variant you order.

Typical applications
With its 60 V drain–source rating the 25N06 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 low 0.048 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 90 ns and an output capacitance (Coss) of 320 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the 25N06
A drop-in substitute for the 25N06 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 25 A and an on-resistance no higher than 0.048 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO-220 and TO-252 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 25N06?
The 25N06 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 25 A continuous drain current.
What is the maximum voltage of the 25N06?
The 25N06 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 25N06 handle?
It is rated for 25 A of continuous drain current, with power dissipation limited to 90 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the 25N06?
On-resistance (Rds(on)) is 0.048 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the 25N06 come in?
It is listed in TO-220 and TO-252. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the 25N06?
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.
