The CS3N50DF with MOSFET TO-220F RoHS is a small-size energy advantage MOSFET made by Convert Semiconductor. It is designed for higher frequency applications, and is rated to 200 volts and 50 amps, with an ability to produce three times the power density compared to standard MOSFETs. The CS3N50DF is compliant with the RoHS (Restriction of Hazardous Substances) Directive, meaning it does not contain prohibited materials such as lead, mercury, chromium, and cadmium. Its features include improved RDS(on) x Qg performance, low gate charge, fast switching speed, and an integrated ESD (electrostatic discharge) protection diode.
