The JCS10N65FT-220MF is a MOSFET N Trench 650V 9.5A (Tc) 4.5V @ 250uA 950 m? @ 4.75A, 10V TO-220MF RoHS manufactured by Jilin. This component is a MOSFET, or a Metal Oxide Semiconductor Field Effect Transistor, which is a type of switch designed for switching DC and low frequency AC signals. It works by using an electric field to control the flow of current and has a number of Input/Output pins which allow it to be connected with other components. The JCS10N65FT-220MF features a 650V 9.5A (Tc) 4.5V @ 250uA 950 m? @ 4.75A, 10V rating, meaning that it is capable of handling 9.5A of direct current with a voltage rating of 650V. Additionally, it has a 4.5V @ 250uA 950 m? @ 4.75A, 10V rating for AC signals, which means that it is capable of handling 4.5V of alternating current at 250uA and 950 m? at 4.75A, 10V. The component also features a TO-220MF RoHS package; this means that it is RoHS (Restriction of Hazardous Substances) compliant and encased in a TO-220 pin package, which allows the component to be connected to a circuit board.
