CRTT056N06N MOSFET — Specifications & Equivalents

About the CRTT056N06N

The CRTT056N06N is a MOSFET with a drain–source voltage (V_DS) rating of 60 V and a continuous drain current (I_D) of 110 A. It can dissipate up to 137 W and is rated to a junction temperature of 150 °C. It is supplied in the TO220 package.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 60 V
• Max continuous drain current (I_D): 110 A
• Power dissipation (P_D): 137 W
• Max junction temperature (T_J): 150 °C
• Package: TO220

Typical applications

With its 60 V drain–source rating the CRTT056N06N sits in the mid-range class of switching MOSFETs, typically found in 24 V and 48 V industrial and battery systems, motor drives and H-bridges and load and hot-swap switching.

The 110 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 ±25 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Switching behaviour is characterised by an output capacitance (C_oss) of 521 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the CRTT056N06N

A drop-in substitute for the CRTT056N06N should match its polarity and offer a drain–source rating of at least 60 V and a continuous drain current rating of at least 110 A.

Mechanically, check the replacement against the TO220 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 CRTT056N06N?

The CRTT056N06N is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 110 A continuous drain current.

What is the maximum voltage of the CRTT056N06N?

The CRTT056N06N has a maximum drain-source voltage (Vds) of 60 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.

How much current can the CRTT056N06N handle?

It is rated for 110 A of continuous drain current, with power dissipation limited to 137 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the CRTT056N06N come in?

It is listed in TO220. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the CRTT056N06N?

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.
