I should turn on a load some LED lamps in paralel with a Mosfet. If it is not there, the gate will not datsheet any voltage from the 12 V power source.

What type of step up converter are you using? Not sure though what bridge you need. See the reference below:. I am using this converter: So the currents you are quoting are with a full supply voltage across the FET for a very short time. Somehow Logic P channel mosfetsarent as plentiful.

Thanks, I learnt few things in my new journey. These transistors will invert the signal from the N-channel mosfet, ensuring no short circuits could happen. The datasheet mentioned a current between 21 Amperes Amperes for itf9622 led. But where can I find K in the datasheet? So, the bottom line is: But then again, if bought at the right place. Is this what you mean?

That is always a special situation coz of the huge spikes you can get in the coil. A logic level mosfet means that it is designed to turn on fully from the logic level of a microprocessor. Oh i fully agree David. Sadly though it can daatsheet dissipate some 80 Itf9622 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.

Thanks — You are correct. Use a baseresistor of say Ohm.

I noticed that the range is very low. It shows the same behaviour when Daatsheet use 3. Should you however be stuck with a FET like the IRF that really needs a high voltage to switch efficiently then use the following circuit: Also, from the graphs, Ids changes with Vds, is it because of the channel shortening effect?

Thanks for pointing out that series. How can I find the current in the LED? You are limited to a current of about mA. Glad to be able to contribute! Some people however have trouble reading a datasheet or do not know what to look for and in that case ifr9622 with TTL level FETs is a safe option.

You will find the print design here.


I had a IRF Mosfet but now i understand why it became very hot. If you are using this circuit to switch any serious loads, then it is wise to solder some thick wire over the tracks coming from the MOSFET. It seems mosfet get burned satasheet time. Perhaps it is a lose wire or something. You are commenting using your WordPress. Please bear in datassheet that eventhough a logic level FET, the IRLN is not at its lowest resistance at 5 Volt, but it shld be low enough to make 10 dtaasheet no problem.

What kind of lamp is it? Thank you for the clear explanation. Joe, good idea, but as I picture your changes, the emittor will be at 12 Volt when open, while yr Arduino will set the basis at a max of 5Volt, which would cause the transistor to close again. I will try it again after soldering it instead of using a breadboard.

I can imagine that a SOT23 indeed can only take a current the size of 7 amps if there hardly is any dissipation read low RDSon. The relatively cheap BUZ11 is also an option. Notify me of new posts via email. The is somewhat better:
