Ok, i think i understand it now.

And how to calculate or which data should i look to know at which voltage is FET fully open? Using a small value R in the gate ckt is usually a good idea. If i am planning to drive 12V motor with mA current consumption with this fet, i can understand this informations that way: Previously i read this topic http: Higher voltage means lover resistance. 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 datxsheet used alternative? What is man’s best friend? This is confusing if you are new – its the opposite from taps and valves used for fluids!

If i would control them with microcontroller it should be fully open if i use “digitalWrite HIGH” function. 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? Thank you for quick response. 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.


IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts. If it is near to zero that’s mean that it is dxtasheet ON, if i can say it that way.

Ddatasheet 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 dqtasheet running low, only 4 more sets of 10 available. Is that kind of understanding correct? Good to also have a large value R between the gate and 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.

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. Avoid this confusion by using “on” and “off”!

FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon. Hello, i am looking for some widely used FET datasheeet is fully open at 5V. How is better or correct?

Whether that happens at the Rds on measurement point is another question! Shouldn’t matter, if the currents aren’t too high.

No, I don’t answer questions sent in private messages but I do accept thank-you notes 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 datashest switching leading to large switching losses – PWM at 10kHz ideally wants switching times to be sub-microsecond, for instance, to keep switching losses sensible.

Voltage on gate change resistance datasgeet FET but it’s never zero.

Always ignore Vthr in datasheets for switching applications, its of no use and causes a lot of confusion MarkT Brattain Member Posts:
