Sino-MicroelectronicsThe JCS4N60FB-220MF with MOSFET N Trench 600V 4A (Tc) 4V @ 250uA 2.4 Ω @ 2A,10V TO-220MF RoHS is a type of semiconductor device manufactured by Jilin Sino-Microelectronics. It is a transistors with a metal-oxide-semiconductor field-effect transistor (MOSFET) which can switch high-power and high voltages up to 600V. This type of transistor has four terminals: gate, drain, source, and substrate. The gate, which is controlled by a small current, determines whether current flows through the transistor. The drain and source are the positive and negative terminals of the transistor, respectively. The substrate is the body of the transistor which serves to connect the internal parts. This device has a fast switching speed, high breakdown voltage, low on-state resistance, and low gate charge, making it suitable for various power applications. In addition, it is RoHS compliant.
