Good to also have a large value R between the gate and gnd to hold the Mosfet off in case the input is floating. Previously i read this topic http: Is that kind of understanding correct?

This is confusing if you are new – its the opposite from taps and valves used for fluids!

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. MarkT Brattain Member Posts: What is man’s best friend?

Whether that happens at the Rds on measurement point is another question! Higher voltage means lover resistance. 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 datahseet ideally wants switching times to be sub-microsecond, for instance, to keep switching losses sensible.


Always ignore Vthr in datasheets for switching applications, its datashfet no use and causes a lot of confusion How is better or 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.

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?

FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon. Ok, i think i understand it now. Generally a ohm gate resistor will protect the Arduino pin when connected to a high current MOSFET dtasheet can have many nF of gate capacitance, the resistor means the current rating for the Arduino pin won’t be exceeded during switching.

Voltage on gate change resistance of FET but it’s never zero. How can dahasheet calculate maximum PWM frequency for stable running? And how to calculate or which data should i look to know at which voltage is FET fully open?

If it is near to zero that’s mean that it is turned ON, if i can say it that way. If i would control them with microcontroller ifl2505 should be fully open if i use “digitalWrite HIGH” function.


Avoid this confusion by using “on” and “off”! Hello, i am looking for some widely used FET which is fully open at 5V.

IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts. Using a small value R in the gate ckt is usually a good idea. Thank you for quick response. Can you suggest some cheaper and widely used alternative?

Shouldn’t matter, if the currents aren’t too high. 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. If i am running it from Arduino it should be fully open at 5V. If i am planning to drive 12V motor with mA current consumption with this fet, i can understand this informations that way: No, I don’t answer questions sent in private messages but I do accept thank-you notes
