The 2SK3018 with SOT-23 MOSFETs ROHS manufactured by FUXINSEMI is a type of surface-mount MOSFET (metal-oxide semiconductor field-effect transistor) package. It is a three-terminal current-controlled device that can be used as a voltage-controlled switch or amplifier in electronic circuits. Specifically, this part has ROHS (Restriction of Hazardous Substances) components, meaning that the internal components and materials conform to all toxic chemical and pollution standards of the European Union. The 2SK3018 is equipped with a SOT-23 package, which is a small-sized surface-mount package with three leads, making it ideal for circuit miniaturization. With a Vds (drain-to-source voltage) of 80V and a low RDS (drain-to-source resistance) of 0.017 O, the device is suitable for efficient, high-speed switching operations and can be used for smart phone and tablet power regulation, audio amplifier applications, and DC-DC converters. It is manufactured by Fuxinsemi, a Chinese semiconductor manufacturer that has been producing high-quality, reliable components for the global market since 1998.
