Sign up using Facebook. Feel free to ask me more specific questions! The voltage difference between the “Gate” and the “Source” pin determines how hard this switch is turned on.

If we go above the threshold, the transistor is turns on. Thanks for the reply! I also checked your picture, jrf520n it seems like you wired the transistor up correctly.

But I ir520n figure out the problem. Just as a note to you about Conrad: This cannot be our problem. I’m not even certain they keep track for the on-line supply.

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.

The old transistor doesn’t heat up noticeably.

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. 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!


Take note that this is not a very dztasheet 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. What does the IRFN actually do: Have you tried using the newly bought transistor with the original motor? Email Required, but never shown.

Ill include that in the post. The other comes from the biggest electronics store here in Germany and Austria conrad. So my questions are: Thanks a lot for the detailed post.

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.

If I missed any important information please ask in the comments and I will include it in my post. Using the 9V batterie with the 12V pump works fine but only with the old transistor. Also, learning to read schematics is essential for doing electronics work. Irg520n 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? Please be gentle as I am a total newbie with electronics. Lonely Neuron 5.


Also I couldn’t find the dataseet for the one delivered with the Arduino. I would not have thought about it, but I did try it and you are right! In fact, I have a bag of almost 50 IRFN’s a slightly bigger version of your transistor laying around here in my lab This means that you can apply up datasneet 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.

From way back when I remember quality of even LEDs being questionable.

Apparently the two transistors are not completely identical. These are very usefull parts, and people use them all the time. So it looks like the new transistor can’t handle the 12V?
