This Mosfet has a low gate threshold voltage of only 4V, this means that the Mosfet can be turned on even with 5V from the GPIO pin of microcontrollers like Arduino. It also has a decent on-state resistance of 0.27 Ohms which increases the efficiency of the Mosfet since it will dissipate less heat as loss. The Mosfet can switch loads that consume upto 9.2A continuous current and operate below 100V. The IRF540N is an N-Channel Power Mosfet. Note: Complete technical details can be found at the IRF520 datasheet linked at the bottom of the page It is commonly used with Arduino, due to its low threshold voltage.Rise time and fall time is 30nS and 20nS.Gate threshold voltage (VGS-th) is 4V (max).Drain Source Resistance (RDS) is 0.27 Ohms.

Drain to Source Breakdown Voltage: 100V.

The mosfet has a low gate threshold voltage of 4V and hence commonly used with microcontrollers like Arduino for switching high current loads. The IRF520 is a Power Mosfet with 9.2A collector current and 100V breakdown voltage.
