24NM60L-TQ2-R MOSFET — Specifications & Equivalents

About the 24NM60L-TQ2-R

The 24NM60L-TQ2-R is a MOSFET with a drain–source voltage (V_DS) rating of 600 V and a continuous drain current (I_D) of 24 A. It can dissipate up to 176 W and is rated to a junction temperature of 150 °C. It is supplied in the TO-263 package.

Typical applications

With its 600 V drain–source rating the 24NM60L-TQ2-R sits in the high-voltage (offline) class of switching MOSFETs, typically found in primary-side switching in offline SMPS (flyback, forward and quasi-resonant), active PFC boost stages, half-bridge and full-bridge inverters, induction heating and electronic ballasts and BLDC and AC motor drives. The rating leaves usable margin above the ~325 V DC bus obtained by rectifying 230 VAC mains, which is why this class dominates offline power supplies.

Gate drive and switching notes

Keep gate–source voltage within the ±30 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Switching behaviour is characterised by an output capacitance (C_oss) of 1100 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the 24NM60L-TQ2-R

A drop-in substitute for the 24NM60L-TQ2-R should match its polarity and offer a drain–source rating of at least 600 V and a continuous drain current rating of at least 24 A.

Mechanically, check the replacement against the TO-263 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 24NM60L-TQ2-R?

The 24NM60L-TQ2-R is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 600 V drain-source and 24 A continuous drain current.

What is the maximum voltage of the 24NM60L-TQ2-R?

The 24NM60L-TQ2-R has a maximum drain-source voltage (Vds) of 600 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the 24NM60L-TQ2-R handle?

It is rated for 24 A of continuous drain current, with power dissipation limited to 176 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the 24NM60L-TQ2-R come in?

It is listed in TO-263. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the 24NM60L-TQ2-R?

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.
