General Description of P55NF06 MOSFET
The P55NF06 MOSFET is an N-channel power MOSFET that can be used in many different applications. This MOSFET is known for its high drain current andfast switching speedon top of that it has a very low on-resistance that increases the efficiency of this device. According to the datasheet, this MOSFET will start conducting with a small gate voltage of 10V, but the max drain current will flow when the gate voltage is 20V. As this MOSFET is designed for high-power applications this can be driven by a microcontroller or a logic level device.
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. 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 27A constant current. So, if you are looking for a MOSFET to be used with a microcontroller then you should consider the logic-level MOSFET like 2N7002 or IRLZ44N etc. Alternatively, you can also use a driver circuit to provide 10V to the gate pin of this MOSFET using a transistor. The frequency response of this MOSFET is quite good hence it can be used in DC-DC converter circuits also. CityTech BD
Under normal circumstances and without external influence there will no voltage present in the gate of the MOSFET because the MOSFET is consist of a capacitor and that is why we need to pull down the gate of the MOSFET to the ground in order to prevent false triggering of the circuit, as we all know that MOSFET are voltage-controlled devices which means to turn off the MOSFET we need to provide only voltage to the gate and theoretically no current should flow through the gate but practically a small amount of leakage current flow through the gate.
How to use P55NF06 MOSFET
MOSFETs are voltage-controlled devices so to turn them on only a small voltage is necessary. For the P55NF06 MOSFET, the gate turn-on voltage is only 4V, as P55NF06 is an N-channel MOSFET that means it will be on when the gate of the MOSFET is connected to the VCC of the supply and it will be off when its pulled down or it’s connected to ground.
The simulated circuit below shows how this MOSFET behaves when the gate of the basic circuit is connected to the ground and when it’s connected to the VCC of the power supply.
When we turn on the MOSFET by connecting the gate to the supply, the MOSFET will remain on unless the gate voltage of the MOSFET goes below the threshold voltage of the MOSFET. For this P55NF06 MOSFET, this voltage is less than 4V, below this voltage MOSFET will be in its ohomic state and no current will flow through the device. As we have mentioned earlier the gate of the MOSFET should be connected to the ground with the help of a pull-down resistor, as shown in the example circuit, a 10K resistor is used to pull down the gate of the MOSFET to the ground.
