Using correct MOSFET with arduino UNO

[ruilviana]

Hi for all.
I saw several posts here on the forum not recommending the use of the IRF520
with Arduino.
As an electronics expert I agree with the various reasons for this.

This is an example:
"It turns out the IRF520 is a poor choice for use with a 5V arduino,"
Ref:

IRF520 MosFET not a good choice for Arduino use.

There have been a number from posts of folks having issues trying to power some substantial load with an IRF520 MosFet. Assumption: The below addresses the situation when the IRF520 is being operated directly from an Arduino output pin. i.e. Arduino output to the gate of the IRF520. It turns out the IRF520 is a poor choice for use with a 5V arduino, forget even thinking about a 3.3V arduino. The issue is the Arduino output pins does not provide enough voltage to the gate of the IRF520 to adeq…

It turns out that my son got an original "STARTER KIT", and it came with 2 IRF520 Mosfets to be used with the Arduino UNO R3.

As the KIT is from the same manufacturer as the arduino, here are my questions:

Am I wrong in not using the IRF520 with UNO?

Could the kit designers not agree with this restriction on the use of the IRF529 IRF520 with the UNO?

Could it be that none of the people who participated in the KIT project didn't know that this Mosfet was not recommended to use with UNO?

Could it be that they never read the Mosfet datasheet?

Maybe they don't even participate in this forum?

On the page about the book you have these participants, among others:
editors;
Digital fabrication and project management;
Advisor and supporter;
Project testers and proofreaders.

Tks in advance.

All good and commmon questions, but don't expect any answers.

Decent, logic level MOSFETs are cheap and easy to find, e.g. N-Channel MOSFET 60V 30A - COM-10213 - SparkFun Electronics

Note: for some reason Sparkfun decided to drop the "logic level" description from the product page, but the advertised transistors are indeed logic level.

Life can suck . . .

FYI, some MOSFETs that work(ed) for me.

But - it that manufacturer Arduino.cc or someone else?

The IRF520 modules will work with a 5 V logic Arduino, up to about one Amp or so according to the datasheet.

IF529?

What "restriction" exactly?

OK now, here's the situation. A heap of little modules are manufactured in China. I do not know - and it is not worth my time to research, but someone may have a better idea - who originally designed and started to manufacture these but I suspect there were not specifically designed to match the Arduino project. There are other and earlier microcontroller projects, the PICs used to be the fashion but have largely faded - I think.

In any case while Arduino is popular, it is not the only "maker" event.

There is a suggestion or implication that the IRF520 modules are nothing more than a means to "pass off" somewhat obsolete devices from original mass manufacture - what are the date codes?

There most certainty are readily available modules using genuine logic level FETs.
