IRF Datasheet(PDF) – International Rectifier

Email Required, but never shown. You cannot drive the IRF in the manner shown.

I suspected the transistor to be broken, but I switched it out several times and the results were the same. When I connected the gate pin of the transistor directly to the 12V power source the circuit worked as intended and the valve opened.

IRF Transistor: correct threshold voltage – Electrical Engineering Stack Exchange

If the circuit is connect as in the picture only dta. Post as a guest Name. Thanks a lot, now the circuit works exactly as I wanted!

The LED is to easily see if the valve is open or closed.

Home Questions Tags Users Unanswered. I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had. My basic idea is that if the soil gets to dry the arduino sets the gate voltage, which turns the transistor irf320 and the valve opens.

However I build the exact same project some jrf3205 ago and used the exact same parts – the same irrf3205, the same transistor type and the same valve and it worked perfectly with a 5V gate voltage. Looking at the details in the datasheet you need to understand that the V GS is applied between the Gate and source of the N-Channel FET, you can look at Figure 1 to see the switching characteristics.



Try your circuit in this form: I built this circuit ir3f205 part of an automatic irrigation system and I am not sure how high the gate voltage should be: Running your Arduino at 5 V this should work ok out to a couple of Amps.

The 5 volts seem to be to low to let enough current flow for the valve, which drains around 2.
