WebPower MOSFETs generally have a RDS (on) value of less than 0.01Ω which allows them to run cooler, extending their operational life span. One of the main limitations when using a MOSFET as a switching device is the maximum drain current it can handle. WebRds(on) of 120mOhms is quite large, and this is the parameter which determines the efficiency and how hot your MOSFET will be during normal operation. Datasheet of NTF3055L108 specifies characteristics at Vgs of 5v, so 3.3v may be slightly lower than desired( with even higher Rds(on) As for PWM - absolutely yes, it would work.

WebFeb 14, 2006 · RDS (on) is the Drain-Source resistance, typically specified on datasheets at 25°C with VGS = 10V for standard Gate MOSFETs [5]. RDS (on) along with Drain current define MOSFET conduction losses during amplifier operation, and can be calculated as follows: RDS (on) is temperature-dependent, increasing when TJ increases. WebRds(on) determines how much power the MOSFET will dissipate and whether you will need heat-sinking (not for a 100mA load, of course). Many high-power MOSFETs require a fairly high Vgs voltage to fully open, you should look for a "logic level" MOSFET if you're driving it directly from an Arduino or other MCU.
