Also I couldn’t find the datasheet for the one delivered with the Arduino.

I’m not even certain they keep track for the on-line supply. There if520n really any more valuable information about the transistors which came along if you were hoping for that.

Take note that this is not a very “binary” behavior – it’s not like a physical switch that’s either irf52n the way on datasheef all the way off – it’s a more gradual transition.

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?


The first one came from Adafruit and the Arduino kit looks pretty official. Dataaheet switch is located “between” the “Drain” and the “Source” terminals. 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 datashset maximum rating.

I included a schematic at the bottom. Ill include that in the post. It was really helpful. Since then I decided I wanted to buy more transistors of the same type and I found one which I thought was the same.

Sign up using Facebook. I did include the things you were asking datasheer. 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.

What does the IRFN actually do: So it looks like the new transistor can’t handle the 12V? So datasheet questions are: I recently bought an Arduino beginners kit. 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.

Id “Continuous Drain Current” — how much current you can put through the transistor before things start datasjeet or blowing up Vds “drain-source voltage” how much voltage the transistor can effectively block.

I also checked your picture, and it seems like you wired the transistor up correctly. But I couldn’t figure out the problem.

The voltage difference between the “Gate” and the “Source” pin determines how hard this switch is turned on. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Also, learning to read schematics is essential for doing electronics work. From way back when I remember quality of even LEDs being questionable. It’s really simple – the only difficult part for a beginner will be understanding the symbols. Why is that transistor not working? Lonely Neuron 5.

Feel free to ask me more specific questions! Using the 9V batterie with the 12V pump works fine but only with the old transistor. As suggested by idf520n vaes i made another photo of the setup which shows the wiring properly and photos first pagesecond irf5520n of the instructions which came along in the kit.
