Why is that transistor not working? I’m not even certain they keep track for the on-line supply. These orf520n very usefull parts, and people use them all the time. They do not practise any quality control or in-store stock tracking, so you cannot always be fully certain the device you got “offline” fits the datasheet, as batches may be mixed.
I have started my own little project and bought a 12V pump and hooked it up just as I previously did with the motor from the kit and it worked perfectly see picture. Also, learning to read schematics is essential for doing electronics work. I would say, dataheet 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.
I recently bought an Arduino beginners kit. Also I couldn’t find the datasheet for the one delivered with the Arduino. If I missed any important information please ask in the comments and I will include it in my post.
Perhaps also point to the location of the tutorial you started out with, irf520h you how to wire up the mosfet in the urf520n experiment.

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? 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.
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. Email Required, but never shown.

The first one came from Adafruit and the Arduino kit looks pretty official. I found the datasbeet 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.
This pinout is different for different parts and different manufacturers, so it’s a good idea to verify this from the manufacturers’ datasheet every time you are using a new part. But I couldn’t figure out the problem.
Lonely Neuron 5. There isn’t really any more valuable information about the transistors which came along if you were hoping for that. If we go above the threshold, the transistor is turns on. Just as a note to you about Conrad: 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.
Please be gentle as I am a total newbie with electronics. With the new transistor the pump moves super slow and the transistor got worryingly hot.
To my surprise that actually made the motor spin. What does the transistor actually do which I bought and can I still use it for something I actually bought quite a lot of them. As joren vaes suggested I used the new transistors with the old motor and a 9V power supply. 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.

I also included some info about an experiment I did with pump and 9V. So my questions are: I would just like to add that another very important bit of information in the datasheet is the pinout – in our case the Gate is pin 1, Drain is pin 2, Source is pin 3.
From way back when I remember quality catasheet even LEDs being questionable.
