Realise though that it is an inverting circuit. Alin Jul 20 ’11 at 9: It could be made to work if it was all you had but there are much much much more suitable FETs available, probably at little or no extra cost. I’m working on controlling the supply of an amplifier board with 5V 2. Indeed, more and more FETs availablefor 3.

Sorry for the stupid questions. Post as a guest Name. In my schematic I use an output with a small resistor Ohms in series with the gate of the 4n3 Channel Mosfet STP3NA and my load is in drain like the first schematic showed in this post, but I have no R1 resistor between gate and source, I only have a resistor like R1 in the second schematic.
The resistor values have the following requirements: Now with Unlimited Eagle board sizes! Sadly though it can only dissipate some 80 Watts There is the MTB60N05HD L that does 60 amps 50 Volt and Amps beware of the somewhat high input capacutance, bu thta does not need to be a huge problem in simple switching also you may consider browsing through this guide.
I would like to use it to switch car heated seat 12V, 8A. I explain another way non-inverting to connect it in my answer. This is for direct transfer so it is already mirrorred the right way. I don’t mosfer if it can work and I can’t understand why the 6N is considered as an “inverting optocoupler”.
Without this the system will die almost instantly. By continuing to n435 this website, you agree to their use.

Using MOSFETS with TTL levels (5 Volt and 3.3 Volt)
Swap the opto transistor with R Would like to have a non inverting driver, do you have any recommendation how to solve this, or best IC driver for arduino.
Please bear in mind that eventhough a logic level FET, the IRLN is not at its lowest resistance at 5 Msofet, but it shld be low enough to make 10 amp no problem. Very good article, thanks for talking about a subject often overlooked by many. If you feed it with 15Volt the output voltage is around volt which will do the job.
Does not make a difference. Apologies foe my kosfet reply. Personally, I would probably add a ohm power resistor, but that would waste power to give myself piece of mind. The irf doesnt need 20 Volt tu turn on. True is that car heated seat is not a very demanding load when properly controlled. Are the parts adequate or are there better options out there?
