MarkT Brattain Member Posts: 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.

No, I don’t answer questions irl25505 in private messages but I do dstasheet thank-you notes How is better or correct?

If i am planning to drive 12V motor with mA current consumption with this fet, i can understand this informations that way: If it is near to zero that’s mean that it is turned ON, if i can say it that way. 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? If i would control them with microcontroller it should be fully open if i use “digitalWrite HIGH” function.


Thank you for quick response. What is man’s best friend? Avoid this confusion by using “on” and “off”! Voltage on gate change resistance of FET but it’s never zero.

Always ignore Vthr in datasheets for switching applications, its of no use and causes a lot of confusion This is confusing if you are new – its the opposite from taps and valves used for fluids! 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.

And how to calculate or which data should i look to know at which voltage datqsheet FET fully open? Is that kind of understanding correct? Higher voltage means lover resistance.

Shouldn’t matter, if the currents aren’t too high. Previously i read this topic http: Ok, i think i understand it now.

How can i calculate maximum PWM frequency for stable running? 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 dafasheet of 10 available.


Whether that happens at the Rds on measurement point is another question! If i am running it from Arduino it should be 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 dwtasheet rating for the Arduino pin won’t be exceeded during switching. 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.

Can you suggest some cheaper and widely used alternative? Hello, i am looking for some widely used FET which is fully open at 5V.

Good to also have a large value R between the gate and gnd to hold the Mosfet off in case datasheeet input is floating. Using a small value R in the gate ckt is usually a good idea.

FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon. IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts.
