IRCP450 MOSFET — Specifications & Equivalents

About the IRCP450

The IRCP450 is an N-channel MOSFET with a drain–source voltage (V_DS) rating of 180 V, a continuous drain current (I_D) of 14 A and an on-resistance (R_DS(on)) of 0.4 Ω. It can dissipate up to 180 W and is rated to a junction temperature of 150 °C. It is supplied in the TO247 package.

Typical applications

With its 180 V drain–source rating the IRCP450 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 an output capacitance (C_oss) of 960 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the IRCP450

A drop-in substitute for the IRCP450 must be the same N-channel type and offer a drain–source rating of at least 180 V, a continuous drain current rating of at least 14 A and an on-resistance no higher than 0.4 Ω if efficiency and heat matter.

Mechanically, check the replacement against the TO247 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 IRCP450?

The IRCP450 is an N-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 180 V drain-source and 14 A continuous drain current.

What is the maximum voltage of the IRCP450?

The IRCP450 has a maximum drain-source voltage (Vds) of 180 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the IRCP450 handle?

It is rated for 14 A of continuous drain current, with power dissipation limited to 180 W. Real-world capability depends on your heatsinking and ambient temperature.

What is the on-resistance of the IRCP450?

On-resistance (Rds(on)) is 0.4 Ω. Multiply by the square of your load current to estimate conduction loss.

What package does the IRCP450 come in?

It is listed in TO247. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the IRCP450?

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.
