An N-channel silicon power MOSFET is a type of metal-oxide-semiconductor field-effect transistor (MOSFET) that utilizes an N-channel region as the conducting channel. It is commonly used in power electronic circuits for applications such as power amplification, switching, and voltage regulation. […]

(1) N-Channel Configuration: The “N-channel” refers to the type of channel formed within the MOSFET. In an N-channel MOSFET, the channel is created in an N-type semiconductor material. When a positive voltage is applied to the gate terminal, it forms an electric field that controls the current flow between the source and drain terminals.
(2) Silicon Technology: The MOSFET is fabricated using silicon as the semiconductor material, which offers good electrical characteristics, high temperature tolerance, and high breakdown voltage capabilities.
(3) Power Handling Capability: N-channel power MOSFETs are specifically designed to handle higher power levels. They have a higher current-carrying capacity compared to small-signal MOSFETs, making them suitable for power applications.
