25N10G-TF1-T MOSFET — Specifications & Equivalents

About the 25N10G-TF1-T

The 25N10G-TF1-T is a MOSFET with a drain–source voltage (V_DS) rating of 100 V and a continuous drain current (I_D) of 23 A. It can dissipate up to 50 W and is rated to a junction temperature of 150 °C. It is supplied in the TO-220F package.

Typical applications

With its 100 V drain–source rating the 25N10G-TF1-T 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 270 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the 25N10G-TF1-T

A drop-in substitute for the 25N10G-TF1-T should match its polarity and offer a drain–source rating of at least 100 V and a continuous drain current rating of at least 23 A.

Mechanically, check the replacement against the TO-220F 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 25N10G-TF1-T?

The 25N10G-TF1-T is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 100 V drain-source and 23 A continuous drain current.

What is the maximum voltage of the 25N10G-TF1-T?

The 25N10G-TF1-T 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 25N10G-TF1-T handle?

It is rated for 23 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 25N10G-TF1-T come in?

It is listed in TO-220F. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the 25N10G-TF1-T?

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.
