IPF06N03LA MOSFET — Specifications & Equivalents

About the IPF06N03LA

The IPF06N03LA is a MOSFET with a drain–source voltage (V_DS) rating of 25 V and a continuous drain current (I_D) of 50 A. It can dissipate up to 83 W and is rated to a junction temperature of 175 °C. It is supplied in the TO252 package.

Typical applications

With its 25 V drain–source rating the IPF06N03LA sits in the very-low-voltage class of switching MOSFETs, typically found in battery protection and power-path switching, point-of-load converters and logic-level load switching in portable devices.

The 50 A current rating puts it in high-current territory, where conduction loss (I² × R_DS(on)) and thermal design usually matter more than switching loss. Budget for adequate copper area and a heatsink.

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 800 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the IPF06N03LA

A drop-in substitute for the IPF06N03LA should match its polarity and offer a drain–source rating of at least 25 V and a continuous drain current rating of at least 50 A.

Mechanically, check the replacement against the TO252 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 IPF06N03LA?

The IPF06N03LA is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 25 V drain-source and 50 A continuous drain current.

What is the maximum voltage of the IPF06N03LA?

The IPF06N03LA has a maximum drain-source voltage (Vds) of 25 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the IPF06N03LA handle?

It is rated for 50 A of continuous drain current, with power dissipation limited to 83 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the IPF06N03LA come in?

It is listed in TO252. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the IPF06N03LA?

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.
