About the IRF5210
The IRF5210 is a P-channel MOSFET with a drain–source voltage (VDS) rating of 100 V, a continuous drain current (ID) of 40 A and an on-resistance (RDS(on)) of 0.06 Ω. It can dissipate up to 200 W and is rated to a junction temperature of 175 °C. It is supplied in the TO220AB package.

Typical applications
With its 100 V drain–source rating the IRF5210 sits in the medium-voltage class of switching MOSFETs, typically found in 48 V and 96 V distribution systems, solar and telecom power stages, DC motor drives and intermediate-bus DC-DC converters.
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 86 ns and an output capacitance (Coss) of 790 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the IRF5210
A drop-in substitute for the IRF5210 must be the same P-channel type and offer a drain–source rating of at least 100 V, a continuous drain current rating of at least 40 A and an on-resistance no higher than 0.06 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO220AB 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 IRF5210?
The IRF5210 is a P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 40 A continuous drain current.
What is the maximum voltage of the IRF5210?
The IRF5210 has a maximum drain-source voltage (Vds) of 100 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the IRF5210 handle?
It is rated for 40 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 IRF5210?
On-resistance (Rds(on)) is 0.06 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the IRF5210 come in?
It is listed in TO220AB. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the IRF5210?
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.
