I would very much doubt that the transistors are very different. I would not have thought about it, but I did try it and you are right! Why is that transistor not working?

It works with the original motor and a 9V battery which runs on 9V. 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.

Since then I decided I wanted to buy more transistors of the same type and I found one which I thought was the same. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Post as a guest Name.

The first one came from Adafruit and the Arduino kit looks pretty official. If we go above the threshold, the transistor is turns on.

The old transistor doesn’t heat up noticeably. ddatasheet

Also I couldn’t find the datasheet for the one delivered with the Arduino. 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. It’s really simple – the only difficult part for a beginner will be understanding the symbols.

This cannot be our problem. Just as a note to you about Conrad: Email Required, but never shown. As joren vaes suggested I used the new transistors with the old motor and a 9V power supply.

Ill include that in the post.

I know that I wouldn’t need an Arduino for that ; Edit 3: The switch is located “between” the “Drain” and the “Source” terminals. Sign up dtasheet Facebook. Could you point out which values in the datasheet are important to me so I can pay attention to those when Daatasheet look for another transistor? 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 did include the things you were asking for. Sign up using Email and Password.

If I missed any important information please ask in the comments and I will include it in my post. Joren Vaes 8, 15 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.


But I couldn’t figure out the problem. 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 ifr520n voltage as part of your circuit!

Home Questions Tags Users Unanswered. 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 know that I wouldn’t need an Arduino for that. So it looks like dataxheet new transistor can’t handle the 12V? 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.

So my questions are: 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.

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 datashset mixed. Have you tried using the newly bought transistor with the original motor? In fact, I have a bag of almost 50 IRFN’s a slightly bigger version of your transistor laying around here in my lab
