Working Principle

NVP4805NT4G is a MOSFET device. In simple terms, it is a switch that can turn on/off flow of signal with varying voltage. MOSFETs are voltage controlled devices with four terminals: gate, drain, source, and body. The two important parameters of a MOSFET are gate-source voltage (VGS) and drain-source voltage (VDS) The drain current (ID) of the MOSFET can be controlled by raising or lowering the gate voltage (VGS). When VGS is below the threshold voltage (VTH) of the MOSFET, the device is said to be in the off-state and no current flows through the drain-source channel. When VGS is increased beyond VTH, the device is said to be in the on-state and electrons will be able to flow through the channel, thus allowing current to flow in the drain-source channel.

Conclusion

The NVP4805NT4G is an advanced MOSFET device designed for power amplifier, automotive power control, lighting, and small signal control circuits. It features exceptional performance features with low on-state resistance, fast-switching performance and high dV/dt capability. The functioning principle behind the MOSFETs is that the capacitance between the gate and source terminals is varied with the application of a controlling voltage in order to alter the current flow from drain to source.
