IRCP340 MOSFET — Specifications & Equivalents

About the IRCP340

The IRCP340 is a MOSFET with a drain–source voltage (V_DS) rating of 150 V and a continuous drain current (I_D) of 10 A. It can dissipate up to 150 W and is rated to a junction temperature of 150 °C. It is supplied in the TO247 package.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 150 V
• Max continuous drain current (I_D): 10 A
• Power dissipation (P_D): 150 W
• Max junction temperature (T_J): 150 °C
• Package: TO247

Typical applications

With its 150 V drain–source rating the IRCP340 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 IRCP340

A drop-in substitute for the IRCP340 should match its polarity and offer a drain–source rating of at least 150 V and a continuous drain current rating of at least 10 A.

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 IRCP340?

The IRCP340 is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 150 V drain-source and 10 A continuous drain current.

What is the maximum voltage of the IRCP340?

The IRCP340 has a maximum drain-source voltage (Vds) of 150 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the IRCP340 handle?

It is rated for 10 A of continuous drain current, with power dissipation limited to 150 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the IRCP340 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 IRCP340?

This page lists 17 candidate equivalents matched on electrical ratings and package. Any replacement should meet or exceed the original voltage, current and dissipation figures and use a compatible drive level.
