Given below are the technical specifications of 2N7002 in a Tabular form. If you are designing a PCB or Perf board with this component then the following picture from the IRF520 Datasheet will be useful to know its package type and dimensions.Controls the MOSFET, used to turn it on and off.Ĭurrent flows through the Drain, usually connected to a load(P-channel).Ĭurrent comes out of transistor through the emitter, usually grounded(P-channel). Added to this the mosfet also has good switching speeds and hence can be used in DC-DC converter circuits also. So if you are looking for a Mosfet to be used with microcontroller then you should consider the logic level Mosfet like 2N7002 etc.Īlternatively you can also use a driver circuit to provide 10V to the gate pin of this Mosfet using a transistor. But this does not mean that the Mosfet will turn on completely with just 5V, it needs around 10V supplied to the gate pin to turn on completely and supply 9.2A collector current. 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.
