IRLU3410P MOSFET — Specifications & Equivalents

About the IRLU3410P

The IRLU3410P is a MOSFET with a drain–source voltage (V_DS) rating of 100 V and a continuous drain current (I_D) of 15 A. It can dissipate up to 61 W and is rated to a junction temperature of 175 °C. It is supplied in the TO251 package.

Typical applications

With its 100 V drain–source rating the IRLU3410P 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 110 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the IRLU3410P

A drop-in substitute for the IRLU3410P should match its polarity and offer a drain–source rating of at least 100 V and a continuous drain current rating of at least 15 A.

Mechanically, check the replacement against the TO251 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 IRLU3410P?

The IRLU3410P is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 15 A continuous drain current.

What is the maximum voltage of the IRLU3410P?

The IRLU3410P 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 IRLU3410P handle?

It is rated for 15 A of continuous drain current, with power dissipation limited to 61 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the IRLU3410P come in?

It is listed in TO251. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the IRLU3410P?

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.
