Daatsheet datasheet indicates max Vgs 4V but the curve shows that at 5V datashee mosfet can deliver current way above my requirement Thank you for your help. I can imagine that datssheet SOT23 indeed can only take a datqsheet the size of 7 amps if there hardly is any dissipation read low RDSon.

Antonio, thank you for expanding. The is somewhat better: Im actualy pondering the same question as Legolas. Hello — Great post! Fill in your details below or click an icon to log in: If the steppermotor does not draw too much, think about an ULN The IRF can obviously take 4 amps, datqsheet sadly it expects a higher voltage on its gate than the most microcontrollers can deliver i presume you will use a microcontroller.

According to your post and the datasheet, the IRLN should have no problem supplying the current at this datashewt, right? Is it possible to use two or maybe three IRF to handle more amperage? I have a hard time believing it would work properly for reasons I explained earlier, but if you say it works for you… great. Thank you for this very good explanation. The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement.


I just touched the gate pin to turn motor on. You are limited to a current of about mA. Another thing to beware of in datasheets is Vthresh threshhold voltage. I even used feedback protective diode with motor. The IRL is a logic level FET and putting 5 Volt on the gate should be enough to open it up, albeit that it has a drain source resistance of less than one ohm, though that depends a bit on the current and the temperature.

It is not a true logic level mosfet, it needs some 10 volts. Glad to be able to contribute!

Iirf9622 presume you are aware of the designcriteria of an H-bridge and the chances of shorting your PSU if you dont do the switching correctly. I should turn on a load some LED lamps in paralel with a Mosfet.

Sorry no T2 and R1. It contains an opto-isolator and does all the gate driving.

You could consider the FQP27P But in reality you dont need that formula as it mainly has to do with the range wherein the FET DrainSource acts as a pure resistor. In my schematic I use an output with a small resistor Ohms in series with the gate of the N 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.


Sadly though it can only dissipate some datashwet Watts There is the MTB60N05HD L that dataseet 60 amps 50 Volt and Dayasheet 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.

The gate source resistor is purely to make a predefined state and to avoid the entrance to float I do not know the PIC18F that well, but what is important is the Output voltage dataaheet has on its pins. For a BC it is a bit on the edge. Thanks very much for your time. If bought per 20 it is 26 eurocts a piece.

Using MOSFETS with TTL levels (5 Volt and 3.3 Volt)

Some people however have trouble reading a datasheet or do not know what to look for and in that case foing with TTL level FETs is a safe option. Normally the impedance of a FET is high enough to not lose any signal over that resistor.

They indeed can stand almost 7A, but only when sufficiently on or off. Then indeed the FET will open but it cannot datxsheet above 5Volt at the source, because then it will close again as the VGStsh is around Do you have any idea why is the mosfet not working properly and letting the 12v works on the led strip?
