About the IRF7220
The IRF7220 is a P-channel MOSFET with a drain–source voltage (VDS) rating of 14 V, a continuous drain current (ID) of 11 A and an on-resistance (RDS(on)) of 0.012 Ω. It can dissipate up to 2.5 W and is rated to a junction temperature of 150 °C. It is supplied in the SO8 package.

Typical applications
With its 14 V drain–source rating the IRF7220 sits in the very-low-voltage class of switching MOSFETs, typically found in battery protection and power-path switching, point-of-load converters and logic-level load switching in portable devices.
The low 0.012 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 ±12 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.
Switching behaviour is characterised by a rise time of 420 ns and an output capacitance (Coss) of 4400 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the IRF7220
A drop-in substitute for the IRF7220 must be the same P-channel type and offer a drain–source rating of at least 14 V, a continuous drain current rating of at least 11 A and an on-resistance no higher than 0.012 Ω if efficiency and heat matter.
Mechanically, check the replacement against the SO8 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 IRF7220?
The IRF7220 is a P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 14 V drain-source and 11 A continuous drain current.
What is the maximum voltage of the IRF7220?
The IRF7220 has a maximum drain-source voltage (Vds) of 14 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the IRF7220 handle?
It is rated for 11 A of continuous drain current, with power dissipation limited to 2.5 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the IRF7220?
On-resistance (Rds(on)) is 0.012 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the IRF7220 come in?
It is listed in SO8. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the IRF7220?
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.
