FDB060AN08A0 MOSFET — Specifications & Equivalents
Manufacturer: Commonly produced by Fairchild (now onsemi)
About the FDB060AN08A0
The FDB060AN08A0 is an N-channel MOSFET with a drain–source voltage (VDS) rating of 75 V, a continuous drain current (ID) of 80 A and an on-resistance (RDS(on)) of 0.006 Ω. It can dissipate up to 255 W and is rated to a junction temperature of 175 °C. It is available in TO263 and D2PAK packages, so confirm the pinout of the exact variant you order.

Typical applications
With its 75 V drain–source rating the FDB060AN08A0 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 80 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 0.006 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.
Choosing a replacement for the FDB060AN08A0
A drop-in substitute for the FDB060AN08A0 must be the same N-channel type and offer a drain–source rating of at least 75 V, a continuous drain current rating of at least 80 A and an on-resistance no higher than 0.006 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO263 and D2PAK 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 FDB060AN08A0?
The FDB060AN08A0 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 75 V drain-source and 80 A continuous drain current.
What is the maximum voltage of the FDB060AN08A0?
The FDB060AN08A0 has a maximum drain-source voltage (Vds) of 75 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the FDB060AN08A0 handle?
It is rated for 80 A of continuous drain current, with power dissipation limited to 255 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the FDB060AN08A0?
On-resistance (Rds(on)) is 0.006 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the FDB060AN08A0 come in?
It is listed in TO263 and D2PAK. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the FDB060AN08A0?
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.
