Glad to be able to contribute!

Thank you for your answer. By continuing to use this website, you agree to their use. If it does open at 3 volt and your PIC supplies that, adding a transistor is not really if1405 and if you do it doesnt need to be the BC, can be a regular signal transistor too, like the We will test them on a heavy load, and see how hot they get with heatsinks.

IRF datasheet & applicatoin notes – Datasheet Archive

That indeed is odd and I start to wonder if datashheet is the IRL that is shutting down or something else. For a mA current you then need a seriesresistor of 33 Ohm. Try just to test without the converter, 3.

Another thing to beware of in datasheets is Vthresh threshhold voltage. That 52 mOhms at 2.

At 5 Volt GS it can however only take some 4. Like the diagram at the top of the page here. Navigation menu Personal tools Log in. Post was not sent – check your email addresses! 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. You may want to read up here https: Looking at those graphs one can see that at a gate to source level of 5V Arduino levels the IRF dayasheet only capable of dataxheet 1 Amp, whereas it is specified for 5,6 Amps continuous current.

But then again, if bought at the right place. Every time I tried with new IRF, but any of them worked only for first time.

Email required Address never made public. So we’ve pretty much settled on the “open source motor controller” design. The more expensive has lower Rds, and the TO package is pretty much limited to 75A of sustained current for thermal reasons, so it will be interesting to see if there’s much performance difference.

The dissipation then is 5x5x0. Thanks again Wayneh and Sgt for your advice. Keep an eye on the temperature though when you start using it with 8 amps. My dilemma is am new to this field so is there any irf1045 better power MOSFET for high voltage switching application and driver for the same.

I will use Arduino to dim the power acording to inputs from handlebar.

This site uses cookies. Im actualy pondering the same question as Legolas. Also, from the graphs, Ids changes with Vds, is it because of the channel shortening effect?


It start switching on at around 3V and it seems to be quite wide open at 4,5V. Use a baseresistor of say Ohm. 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.

More and more cheap Mosfets. Apologies foe my late reply. The device will be either fully on or off as selected.

So, the bottom line is: The only conditions are it should have high switching speed so low rds iirf1405 and high break down voltage.

With regard to 9V and 5V input, I presume you mean supply voltage. Indeed, more and more FETs availablefor 3.

IRF1405 Relay/Switch

At 8A it is not even breaking a sweat. I am not sure if there is an easier way to do it. Nowadays more and more 3. As there is irf4105 LED in the source to ground i presumethere is already a voltage drop, keeping the source above ground.

We need 8 per board, and two boards per orb, so they add up fast.
