I would just like to add that another very important bit of information in the datasheet is the pinout – datashest our case the Gate is pin 1, Drain is pin datasueet, Source is pin 3. 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.

What does the IRFN actually do: 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.

But I couldn’t figure out the problem. There also exist “depletion mode” transistors – here the transistor is already turned on at 0V!

Datashret we go above the datahseet, the transistor is turns on. 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. 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. If I missed any important information please ask in the comments and I will include it in my post.


I also checked your picture, and it seems like you wired the transistor up correctly. I did include the things you were asking for. Also I couldn’t find the datasheet for the one delivered with the Arduino.

From way back when I remember quality of even LEDs being questionable. So my questions are: Lonely Neuron ird520n. It’s really simple – the only difficult part for a beginner will be understanding the symbols.

Just as a note to you about Conrad: I know that I wouldn’t need an Arduino for that ; Edit 3: Email Required, but never shown. They do not practise any quality control or in-store stock tracking, so you cannot always datashete fully certain the device datashdet got “offline” fits the datasheet, as batches may be mixed.

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. So it looks like the new transistor can’t handle the 12V?

Why is that transistor not working? The other comes from the biggest electronics store here in Germany and Austria conrad. Since then Irf5200n decided I wanted to buy more transistors of the same type and I found one which I thought was the same. These are very usefull parts, and people use them all the time. With the new transistor the pump moves super slow and the transistor got worryingly hot. Apparently the two transistors are not completely identical.

Have you tried using the newly bought transistor with the original motor? I know that I wouldn’t need an Arduino for that.

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 old transistor doesn’t heat up noticeably.
