I will try it again after soldering it instead of using a breadboard. It is not a true logic level mosfet, it needs some 10 volts. It seems mosfet get burned every time. Also, if you have the gate floating, the state of the mosfet could be undefined.

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

Yes im using Arduino to control the circuit. The input capacitance is best chosen as low as possible. So if yr gate voltage is 5Volt, your source voltage datssheet never be above that. I have done like you said. How can I find the current in the LED? The circuit should be robust enough to support the load during a few minutes. What kind of lamp is it?

You are commenting using your Twitter account. That is definitely enough for most applications. This will need a good heatsink if the load is on for more than a second or two, but it is no issue if it gets millisecond pulses every few seconds.


Or for a power rectifier? Hi, really interesting your information!! Setting a temperature to a comfortable level arduino switches the mosfet on for sec followed by a 50sec off time. The only caveat using those AO parts, is their size: Sorry no T2 and R1. The is somewhat better: The question is the one joe provided a solution to in an earlier question, except just as you pointed out, his solution doesnt work because the emitter voltage will be close to 12V and the base voltage from the arduino will be 5V so the transistor will close.

A logic level mosfet means that it is designed to turn on fully from the logic level of a microprocessor.

See the reference below: If it is not there, irf622 gate will not get any voltage from the 12 V power source. Thank you for your answer. Do you have the break out board in the drain or the source? The 2n series, often used with the arduino is even worse in that aspect, but if used to switch an LED it is OK rdsOn about ohms at 4.

You may want to read up here https: But then again, if bought at the right place. The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement. Then you can find the current in the datasheet? Realise though that it is an inverting circuit. The IRF can obviously take 4 amps, but sadly it expects a higher voltage on its gate than the most microcontrollers can deliver i presume you will use a microcontroller.


The only conditions are it should have high switching speed so low rds on and high break dataaheet voltage.

It start switching on at around 3V and it seems to be quite wide open at 4,5V. IRFZ44, and you want to switch somewhat higher voltages i.

Nowadays more and more 3. At 5V volt on the gate, the IRF will pass something around 4. Rds irf96622 with a Vgs of 3. It contains an opto-isolator and does all the gate driving. Thanks for pointing out that series.

At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. If for instance you want to switch 5A in a 12V circuit and you only want to waste 0. So no R1 and T1 from your diagram link? I noticed that the range is very low.
