MarkT Brattain Member Posts: What is man’s best friend? Using a small value R in the gate ckt is usually a good idea. Avoid this confusion by using “on” and “off”! I wouldn’t expect to be able to run irl5205 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 datasheef cent each cost.
This is confusing if you are new – its the opposite from taps and valves used for fluids!
Can you suggest some cheaper and widely used alternative? No, I don’t answer questions sent in private messages but I do accept thank-you notes How can i calculate maximum PWM frequency for stable running?
IRL (IRF) – Power Mosfet, N-Channel
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.
FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon. 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. Higher voltage means lover resistance.
Whether that happens at the Rds on measurement point is another question! Good to also have a large value R between the gate and gnd to hold the Mosfet off in case the input is floating. Thank you for quick response.

Shouldn’t matter, if the currents aren’t too high. Previously i dztasheet this topic http: And how to calculate or which data should i look to know at which voltage is FET fully open?
Hello, i am looking for some widely used FET which is fully open at 5V. How is better or correct? Up till now i used IRL but is quite datasheey and i can’t get them from our local electro shop i had to order them from Farnell.
IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts. Generally a ohm gate resistor will protect the Arduino pin when connected to a high current MOSFET they can have many nF datzsheet gate capacitance, the resistor means the current rating for the Arduino pin won’t be exceeded during switching. Is that kind of understanding correct? Ok, i think i understand it now.
If it is near to zero that’s mean that it is turned ON, if i can say it that way. 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: Always ignore Vthr in datasheets for switching applications, its of no use and causes a lot of confusion 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. If i am running it from Arduino it should be fully open at 5V.
