Using a small value R in the gate ckt is usually a good idea.

Higher voltage means lover resistance. And how to calculate or which data datasueet i look to know at which voltage is FET fully open? What is man’s best friend? Hello, i am looking for some widely used FET which is fully open at 5V.

Generally a ohm gate resistor will protect the Arduino pin when connected to a high current MOSFET they can have many nF of gate capacitance, the resistor means the current rating for the Arduino pin won’t be exceeded during switching.

MarkT Brattain Member Posts: No, I don’t answer questions sent in private messages but I do accept thank-you notes FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon. ir2505

Shouldn’t matter, if the currents aren’t too high. Can you suggest some cheaper and widely used alternative? Up till now i used IRL but is quite expensive and i can’t get them from our local electro shop i had to order them from Farnell.

Good to also have a large value R between the gate datashet gnd to hold the Mosfet off in case the input is floating. If i am running it from Arduino it should be fully open at 5V.

Thank you for quick response.

V ds – drain to source means maximum voltage for supplying motor for example V gs – gate to source means maximum voltage for driving FET Is that correct? You might be interested in an ebay offering that another forum member found recently, but the sellers seems to be running low, only 4 more sets of 10 available. I wouldn’t expect to be able to run them at their 12 amp max rating without some serious heatsinking, but for up to a couple of amps or so you can’t beat the 20 cent each cost.

Always ignore Vthr in datasheets for switching applications, its of no use and causes a lot of confusion Ok, i think i understand it now.

Previously i read this topic http: This is confusing if you are new – its the opposite from taps and valves used for fluids! How can i calculate maximum PWM frequency for stable running?

How is better or correct? Voltage on gate change resistance of FET but it’s never zero. Avoid this confusion by using “on” and “off”!

If it is near to zero that’s mean that it is turned ON, if i can say it that way. Is that kind of understanding correct? If i would control them with microcontroller it should be fully open if i use “digitalWrite HIGH” function.

FET recommendation

If i am planning to drive 12V motor with mA current consumption with this fet, i can understand this informations that way: IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts. Whether that happens at the Rds on measurement point is another question!

If you need fast PWM though you’ll need a MOSFET driver chip to boost the current to the gate otherwise the capacitance limits the speed of switching leading to large switching losses – PWM at 10kHz ideally wants switching times to be sub-microsecond, for instance, to keep switching losses sensible.
