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. I hope I didn’t do anything wrong. Joren Vaes 8, 15 Sign up using Email and Password.

Using the 9V batterie with the 12V pump works fine but only with the old transistor. 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. From way back when I remember quality of even LEDs being questionable. 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 itf520n block.

I would usually link to the wikipage, but unfortunatly the one on MOSFETs is really quite complicated and I fear it will dahasheet more harm than good. 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.

To my surprise that actually made the motor spin.

I included a schematic at the bottom. 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! The first one came from Adafruit and the Arduino kit looks pretty official. Thanks a lot for the detailed post. In fact, I have a bag of almost 50 IRFN’s a slightly bigger version of your transistor laying around here in my lab It was really helpful.

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.

Post as a guest Name. The old transistor doesn’t heat up noticeably. Apparently the two transistors are not completely identical. Sign up or log in Sign up using Google.

Email Required, but never shown. 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. But I couldn’t figure out the problem.

If I missed any important information please ask in the comments and I will include it in my post. It works with the original motor and a 9V battery which runs on 9V. 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. But the original transistor totally works with 12V and the pump but the new transistors dont I tried 3 of them, so it can’t be one which shipped broken do the transistors actually only work with 9V and the one I got from the kit just has a higher tolerance?

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.

The voltage difference between the “Gate” and the “Source” pin determines how hard this switch is turned on. I also checked your picture, and it seems like you wired the transistor up correctly. It’s really simple – the only difficult part for a beginner will be understanding the symbols. 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. Ill include that in the post.

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.

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. I did include the things you were asking for.

If this difference is smaller than the “threshold voltage”, found in the datasheet, the switch is “off”. This cannot be our problem. The other comes from the biggest electronics store here in Germany and Austria conrad. I can’t believe that any of the two is. 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.

Just as a note to you about Conrad: Please be gentle as I am a total newbie with electronics. Since then I decided I wanted to buy more transistors of the same type and I found one which I thought was the same. So it looks like the new transistor can’t handle the 12V? So my questions are:
