Hello, i am looking for some widely used FET which is fully open at 5V. If i would control them with microcontroller it should be fully open if i use “digitalWrite HIGH” function. 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.

Ilr2505 you suggest some cheaper and widely used alternative? How is better or correct?

IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts. Shouldn’t matter, if the currents aren’t too high. Using a small value R in the gate ckt is usually a good idea.

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.

Previously i read this topic http: If i am running it from Arduino it should be fully open at 5V. If irl505 am planning to drive 12V motor with mA current consumption with this fet, i can understand this informations that way: Is that kind of understanding correct? And how to calculate or which data should i look to know at which voltage is FET fully open?

No, I don’t answer questions iel2505 in private messages but I do accept thank-you notes MarkT Brattain Member Posts: This is confusing if you are new – its the opposite from taps and valves used for fluids! Avoid this confusion by using “on” and “off”!

Always ignore Vthr in datasheets for switching applications, its of no use and causes a lot of confusion 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. 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 xatasheet times to be sub-microsecond, dayasheet instance, to keep switching losses sensible.

Ok, i think i understand it now. Voltage on dataasheet change resistance of FET but it’s never zero. Higher voltage means lover resistance. 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? How can i calculate maximum Dattasheet frequency for stable running? FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon. Whether that happens at the Rds on measurement point is another question!

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. 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 datwsheet you can’t beat the 20 cent each cost.
