Working Principle
The NTMS4873NFR2G is an N-channel enhancement-mode power MOSFET and utilizes an improved silicon gate structure, allowing the device to deliver superior performance. The gate oxide layer is highly conductive and resistant, while the gate and internal insulation layers are formed using a proprietary high-voltage process. The device consists of one common source electrode which is connected to the drain and gate electrodes. When a voltage lower than the threshold voltage (VGS) is applied to the gate electrode, the MOSFET is switched off and no current flows through the device. When a voltage higher than the threshold voltage (VGS) is applied to the gate electrode, the MOSFET is switched on and current flows through the channel between the source and drain electrodes. It is important to note that the device must be provided with an appropriate gate voltage to ensure that it is properly switching on and off.
