N-channel MOSFETs are not a specific brand but a type of metal-oxide-semiconductor field-effect transistor (MOSFET) widely used in electronics. They are produced by various global semiconductor companies, including Infineon Technologies (Germany), ON Semiconductor (USA), STMicroelectronics (Switzerland/France), and Toshiba (Japan). These components serve industries such as power electronics, automotive, industrial automation, and consumer electronics. Key products include power MOSFETs for switching applications, RF MOSFETs for high-frequency circuits, and integrated modules for efficient energy management. Major manufacturers often provide datasheets and application notes through distributors like Radwell and Grainger, catering to engineers and procurement professionals.
