SQD50N06-07L MOSFET — Specifications & Equivalents

About the SQD50N06-07L

The SQD50N06-07L is a MOSFET with a drain–source voltage (V_DS) rating of 60 V and a continuous drain current (I_D) of 50 A. It can dissipate up to 136 W and is rated to a junction temperature of 175 °C. It is supplied in the TO-252 package.

At a glance

• Type: MOSFET
• Max drain–source voltage (V_DS): 60 V
• Max continuous drain current (I_D): 50 A
• Power dissipation (P_D): 136 W
• Max junction temperature (T_J): 175 °C
• Package: TO-252

Typical applications

With its 60 V drain–source rating the SQD50N06-07L 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 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 407 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.

Choosing a replacement for the SQD50N06-07L

A drop-in substitute for the SQD50N06-07L should match its polarity and offer a drain–source rating of at least 60 V and a continuous drain current rating of at least 50 A.

Mechanically, check the replacement against the TO-252 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 SQD50N06-07L?

The SQD50N06-07L is a MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 50 A continuous drain current.

What is the maximum voltage of the SQD50N06-07L?

The SQD50N06-07L 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 SQD50N06-07L handle?

It is rated for 50 A of continuous drain current, with power dissipation limited to 136 W. Real-world capability depends on your heatsinking and ambient temperature.

What package does the SQD50N06-07L come in?

It is listed in TO-252. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the SQD50N06-07L?

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.
