Something rated V and A and with logic-level drive would be much more useful to you I went to Radio Shack today and picked up a few things that I thought would be helpful and help get me ahead of where I was yesterday: I solved this by simply adding 3 more IRF’s in parallel.

Also of note is that the delay function seems to work just fine if I remove the PWM pin so that it is not connected to anything.

So my next question is what is the proper method for giving a motor more and less power? This happens even if I don’t even have the Ardunio hooked up. How to use IRFN: This is its listing on Ebay: I thought I’d post an update since everyone was so helpful. Customers using or selling Vishay products not expressly indicated for use in such applications do so at their own risk. The water pump is rated at 12V and 2. Submitted by webmaster on 8 December Such statements are not binding statements about the suitability of products for a particular application.


Reliability data for Silicon Technology and Package Reliability represent a composite of all qualified locations. I’d suggest a 1K from 12V to a capacitor to ground. To tackle this we should use a current limiting capacitor, I have a used a value of here. Dataseet alo need to check the data sheet to see how well it performs with only 5v on the gate.

Current flows in through Drain. So if datssheet are looking for a Mosfet to switch applications that consume high current with some logic level devices then this Mosfet will be a perfect choice for you. Another problem you have is that the IRF has an enormous Ron of 0. And Arduino doesn’t have high-voltage tolerant output pins.

This is the source code that I used: It also has a threshold voltage of 4V, which means it can easily driven by low voltages like 5V.

orf840a Use Google Search box in upper right side of this page. I looked at the spec for a the IRF, and it looks like it needs 10V to switch it on.

Both lowered resistance, but still kept maybe 2k ohms. Please note that some Vishay documentation may still make reference to the IEC definition.

Products may be manufactured at one of several qualified locations.

Since this an N-Channel mosfet the load that has to be switched in this case a motor should always be connected above the drain pin. If you are designing a PCB or Perf board with this component then the following picture from the 2N Datasheet will be useful to dxtasheet its package type and dimensions.

I’ve attached an actual picture of what I’m working with. Meaning, they can be turned on or turned off by supplying dattasheet required Gate threshold voltage VGS. This mosfet can drive loads upto 23A and can support peak current upto A.

I didn’t have any luck with the transistors that got from Radio Shack, I actually just ended up getting the original IRFs that I had to work by using 4 in parallel to prevent them from overheating. Drain Current 12 V 0.
