Familiarize Electronic Component Part V – FET and MOSFET


Field Effect Transistor or FET uses an electric field to make it conducting. The electric field changes the shape of its channel and causes its conductivity. MOSFET is the Metal Oxide Semiconductor Field Effect Transistor used for switching applications or to amplify signals. MOSFET is more sensitive and sophisticated than FET.

Power MOSFET


MOSFET is the Metal Oxide Semiconductor Field Effect Transistor used for switching applications or to amplify signals. In the MOSFET, a voltage applied to its oxide- insulated gate to induces a conducting channel between the Source and Drain electrodes. This causes the flow of current. The channel may be n-type or p-type and based on this, MOSFETs may be n-MOSFET or p-MOSFET. Previously, metal was used in the gate but now polysilicon is used in the gate but the efficiency is more in metal made gate channel.
