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 so, what are proper components to use? I’d suggest a idf840a from 12V to a capacitor to ground.

MarkT Brattain Member Posts: You alo need to check the data sheet to see how well it performs with only 5v on the gate. I looked at the spec for a the IRF, and it looks like it needs 10V to switch it on.

Also, I have no idea how to properly use a PNP transistor, I attempted datashedt run the 12V through the PNP and ird840a the Arduino’s 5V to turn it off an on, however this did not seem to datazheet and I ran into all kinds of crazy issues such as power seeming to run back through the gate from the collector. How to use IRFN: I found that “analogWrite 9, ” worked better.

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.


To avoid this problem we datazheet always use a pull-down resistor R1here I have used a value of 10k. Here is the part of the code where the delay is not working, I set it up to eliminate any outside factors: Current flows out through Source. Use Google Search box in upper right side of this page.

Mosfet TO-220 & SMD220 Power MOSFETs

This mosfet can drive loads upto 23A and can support peak current upto A. B, Mar This datasheet is subject to change without notice.

Once I did these things, the resistance seemed to drop to zero when I applied 5V to the gate. If not, what do you do, and again, what are the proper components to use?

Here are some examples, to illustrate what is available http: You simply need to drive its gate from a NPN transistor with pull-up to 12V – however the pump might be putting spikes onto the 12V rail which might be an issue.

It also has a threshold voltage of 4V, which means it can easily driven by low voltages like 5V. When you satasheet on a Mosfet by supplying the required voltage to the gate pin, it will remain on unless you supply 0V to the gate.

I solved this by simply adding 3 more IRF’s in parallel. I thought I’d post an update since everyone was so helpful.

IRFA datasheet, Pinout ,application circuits Mosfet TO & SMD Power MOSFETs

When I first heard of MOSFETs and saw some pictures, I said daatasheet is no way they can carry the load that they are rated at, it takes thick wire datashete carry significant amounts of power, not these tiny little pins Product names and markings noted herein may be trademarks of their respective owners. This is its listing on Ebay: TL — Programmable Reference Voltage. Meaning, they can be turned on or turned off by supplying the required Gate threshold voltage VGS.

The water pump is rated at 12V and 2. I’ve attached an actual picture of what I’m working with.
