F5038H MOSFET — Specifications & Equivalents
About the F5038H
The F5038H is an N-channel MOSFET with a drain–source voltage (VDS) rating of 50 V, a continuous drain current (ID) of 3 A and an on-resistance (RDS(on)) of 0.16 Ω. It can dissipate up to 30 W and is rated to a junction temperature of 150 °C. It is supplied in the TO220F5 package.

Typical applications
With its 50 V drain–source rating the F5038H 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 F5038H
A drop-in substitute for the F5038H must be the same N-channel type and offer a drain–source rating of at least 50 V, a continuous drain current rating of at least 3 A and an on-resistance no higher than 0.16 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO220F5 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 F5038H?
The F5038H is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 50 V drain-source and 3 A continuous drain current.
What is the maximum voltage of the F5038H?
The F5038H has a maximum drain-source voltage (Vds) of 50 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the F5038H handle?
It is rated for 3 A of continuous drain current, with power dissipation limited to 30 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the F5038H?
On-resistance (Rds(on)) is 0.16 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the F5038H come in?
It is listed in TO220F5. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the F5038H?
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.
