Manufacturer: Commonly produced by International Rectifier (now Infineon)
About the IRF9Z15
The IRF9Z15 is a P-channel MOSFET with a drain–source voltage (VDS) rating of 60 V, a continuous drain current (ID) of 4 A and an on-resistance (RDS(on)) of 0.7 Ω. It can dissipate up to 20 W and is rated to a junction temperature of 150 °C. It is supplied in the TO220AB package.

Typical applications
With its 60 V drain–source rating the IRF9Z15 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.
Choosing a replacement for the IRF9Z15
A drop-in substitute for the IRF9Z15 must be the same P-channel type and offer a drain–source rating of at least 60 V, a continuous drain current rating of at least 4 A and an on-resistance no higher than 0.7 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 IRF9Z15?
The IRF9Z15 is a P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 4 A continuous drain current.
What is the maximum voltage of the IRF9Z15?
The IRF9Z15 has a maximum drain-source voltage (Vds) of 60 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the IRF9Z15 handle?
It is rated for 4 A of continuous drain current, with power dissipation limited to 20 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the IRF9Z15?
On-resistance (Rds(on)) is 0.7 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the IRF9Z15 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 IRF9Z15?
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.
