F5030 MOSFET — Specifications & Equivalents
About the F5030
The F5030 is an N-channel MOSFET with a drain–source voltage (VDS) rating of 40 V, a continuous drain current (ID) of 18 A and an on-resistance (RDS(on)) of 0.07 Ω. It can dissipate up to 38 W and is rated to a junction temperature of 150 °C. It is supplied in the TPACK package.

Typical applications
With its 40 V drain–source rating the F5030 sits in the low-voltage class of switching MOSFETs, typically found in 12 V and 24 V automotive and industrial rails, synchronous buck converters, load switching and reverse-polarity protection and H-bridges for small motors.
Choosing a replacement for the F5030
A drop-in substitute for the F5030 must be the same N-channel type and offer a drain–source rating of at least 40 V, a continuous drain current rating of at least 18 A and an on-resistance no higher than 0.07 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TPACK 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 F5030?
The F5030 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 40 V drain-source and 18 A continuous drain current.
What is the maximum voltage of the F5030?
The F5030 has a maximum drain-source voltage (Vds) of 40 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the F5030 handle?
It is rated for 18 A of continuous drain current, with power dissipation limited to 38 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the F5030?
On-resistance (Rds(on)) is 0.07 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the F5030 come in?
It is listed in TPACK. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the F5030?
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.
