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. Voltage on gate change resistance of FET but it’s never zero. If i am planning to drive 12V motor with mA current consumption with this fet, i can understand this informations that way: Ok, i think i understand it now.

Higher voltage means lover resistance. Is that kind of understanding correct? 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? IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts.

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.

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. Shouldn’t matter, if the currents aren’t too high. What is man’s best friend? MarkT Brattain Member Posts: Can you suggest some cheaper and widely used alternative? Avoid this confusion by using “on” and “off”!

Hello, i am looking for some widely used FET which is fully open at 5V. If it is near to zero that’s mean that it is turned ON, if i can say it that way.

If i am running it from Arduino it should be fully open at 5V. 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.

This is confusing if you are new – its the opposite from taps and valves used for fluids! FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon. Using a small value R in the gate ckt is usually a good idea.

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. How can i calculate maximum PWM frequency for stable running?

No, I don’t answer questions sent in private messages but I do accept thank-you notes And how to calculate or which data should i look to know at which ratasheet is FET fully open? Previously i datashee this topic http: Whether that happens at the Rds on measurement point is another question! How is better or correct?

Always ignore Vthr in datasheets for switching applications, its of no use and causes a lot of confusion 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 would control them with microcontroller it should be dtaasheet open if i use “digitalWrite HIGH” function.
