If i would control them with microcontroller it should be fully open if i use “digitalWrite HIGH” function. 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.

Hello, i am looking for some widely used FET which is fully open dztasheet 5V. Whether that happens at the Rds datasehet measurement point is another question!

Previously i read this topic http: How can i calculate maximum Dtasheet frequency for stable running? Using a small value R in the gate ckt is usually a good idea. If it is near to zero that’s mean that it is turned ON, if i can say it that way.


What is man’s best friend? Avoid this confusion by using “on” and “off”! Good to also have a large value R between krl2505 gate and gnd to hold the Mosfet off in case the input is floating.

Higher voltage means lover resistance. And how to calculate or which data should i look to know at which voltage is FET fully open?

You might be interested in an ebay offering that another forum member found recently, but the sellers seems datazheet be running low, only 4 more sets of 10 available. Is that kind of understanding correct? 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 am planning to drive 12V motor with mA current consumption with this fet, i can understand this informations that way: FET’s do become “fully on”, generally Rds on is just the parasitic resistance of the contacts and bulk silicon.

MarkT Brattain Member Posts: Thank you for quick response. Ok, i think i understand it now.

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. Shouldn’t matter, if the currents aren’t too high. IRLs are inexpensive, but will have a larger Rds on than the newer, more expensive parts. Can you suggest some cheaper and widely used alternative?


How is better or correct? 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. If i am running it from Arduino it should be fully open at 5V.

No, I don’t answer questions sent in private messages datashewt I do accept thank-you notes 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. Voltage on gate change resistance of Datasyeet but it’s never zero.

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