This pinout is different for different parts and different manufacturers, so it’s a good idea to verify this from the manufacturers’ datasheet datashedt time you are using a new part.

I’m not even certain they keep track for the on-line supply.

I would usually link to the wikipage, but unfortunatly the one on MOSFETs is really quite complicated and I fear it will do more harm than good. Why is that transistor not working? Could you point out which values in the datasheet are important to me so I can pay attention to those when I look for another transistor?

The big metal tab is also connected to the Drain terminal, internally so watch out when working with the transistor, since this metal piece is at the same voltage as part of your circuit! Depletionmode MOSFETs are very uncommon outside of specialized scenarios – so much so that most people in the last years of the EE bachelors won’t even know they exist, but I felt it was worth mentioning them here, for completeness sake.

HOWEVER, there is a slight possibility that the one you bought has different pin assignments than the original, so you might have it wired wrong. As suggested by joren vaes i made another photo of the setup which shows the wiring properly and photos first pagesecond page of the instructions which came along in the kit. Email Required, but never shown. Id “Continuous Drain Current” — how much current you can put through the transistor before things start melting or blowing up Vds “drain-source voltage” how much voltage the transistor can effectively block.


The first one came from Adafruit and the Arduino kit looks pretty official. Take note that this is not a very “binary” behavior – it’s not like a physical switch that’s either all the way on or all the way off – it’s a more gradual transition.

It was really helpful. It works with the original motor and a 9V battery which runs on 9V.

There also exist “depletion mode” transistors – here the transistor is already turned on at 0V! Post as a guest Name. So it looks like the new transistor can’t handle the 12V? I also checked your picture, and it seems like you wired the transistor up correctly.

In fact, I have a bag of almost 50 IRFN’s irf502n slightly bigger version of your transistor laying around here in my lab These are very usefull parts, and people use them all the time.

So my questions are: Please be gentle as I am a total newbie with electronics. There isn’t really any more valuable information about the transistors which came along if you were hoping for that. I found the datasheet to the newly acquired transistor listed on the page of the online store I bought it from but I don’t really understand anything it’s trying to tell me.

It’s really simple – the only difficult part for a beginner will be understanding the symbols. If we go above the threshold, the transistor is turns on. I know that I wouldn’t need an Arduino for that.

If I missed any important information please ask in the datasheet and I will include it in my irff520n. Apparently the two transistors are not completely identical. Perhaps also point to the location of the tutorial you started out with, telling you how to wire up the mosfet in the original experiment.

I would just like to add that another very important bit of information in the datasheet is the pinout – irf520j our case the Gate is datsaheet 1, Drain is pin 2, Source is pin 3. Feel free to ask me more specific questions! The other comes from the biggest electronics store here in Germany and Austria conrad.

Just as a note to you about Conrad: I hope I didn’t do anything wrong.

I also included some info about an experiment I did with pump and 9V. I can’t believe that any of the two is. I did include the things you were asking for. But I couldn’t figure out the problem. I would very much doubt that the transistors are very different.

This means that you can apply up to 20V difference between pin 1 and 3 on the device – as you mention you were using a 9V battery or a 12V supply, neither of which come close to this maximum rating. What does the IRFN actually do: I would say, take some more pictures of the different setups so we can have a look at those, to try and find out what’s going on here.
