Manufacturer: Commonly produced by International Rectifier (now Infineon)
About the IRFP132
The IRFP132 is an N-channel MOSFET with a drain–source voltage (VDS) rating of 100 V, a continuous drain current (ID) of 12 A and an on-resistance (RDS(on)) of 0.23 Ω. It can dissipate up to 77 W and is rated to a junction temperature of 150 °C. It is supplied in the TO3P package.

Typical applications
With its 100 V drain–source rating the IRFP132 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 34 ns and an output capacitance (Coss) of 240 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the IRFP132
A drop-in substitute for the IRFP132 must be the same N-channel type and offer a drain–source rating of at least 100 V, a continuous drain current rating of at least 12 A and an on-resistance no higher than 0.23 Ω if efficiency and heat matter.
Mechanically, check the replacement against the TO3P 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 IRFP132?
The IRFP132 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 12 A continuous drain current.
What is the maximum voltage of the IRFP132?
The IRFP132 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 IRFP132 handle?
It is rated for 12 A of continuous drain current, with power dissipation limited to 77 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the IRFP132?
On-resistance (Rds(on)) is 0.23 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the IRFP132 come in?
It is listed in TO3P. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the IRFP132?
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.
