APM2014N MOSFET — Specifications & Equivalents

About the APM2014N

The APM2014N is a MOSFET with a drain–source voltage (V_DS) rating of 20 V and a continuous drain current (I_D) of 30 A. It can dissipate up to 50 W and is rated to a junction temperature of 150 °C. It is supplied in the TO252 package.

Typical applications

With its 20 V drain–source rating the APM2014N 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.

Gate drive and switching notes

Keep gate–source voltage within the ±16 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Switching behaviour is characterised by an output capacitance (C_oss) of 300 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the APM2014N

A drop-in substitute for the APM2014N should match its polarity and offer a drain–source rating of at least 20 V and a continuous drain current rating of at least 30 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 APM2014N?

The APM2014N is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 20 V drain-source and 30 A continuous drain current.

What is the maximum voltage of the APM2014N?

The APM2014N has a maximum drain-source voltage (Vds) of 20 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the APM2014N handle?

It is rated for 30 A of continuous drain current, with power dissipation limited to 50 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the APM2014N 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 APM2014N?

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.
