The KNP6140A MOSFET is a three-terminal, insulated-gate field-effect transistor (IGFET) manufactured by KIA. The device is housed in a TO-220 package, which is 3 mm in width, 3 mm in length, and 2.5 mm in height. It features RoHS compliance, and is designed for use in high power switch applications such as voltage regulation, automotive and industrial motor drives, and audio amplifiers. The KNP6140A has a high blocking voltage, low on-resistance, low gate-source capacitance, and low gate charge, making it a suitable choice for high-efficiency and high-temperature operation. The device is capable of handling high current and voltage levels, making it suitable for more demanding applications.
