The SLD5N65S is a MOSFET (metal-oxide-semiconductor field-effect transistor) with TO-252 packaging and RoHS certification, manufactured by Maplesemi. It is a N-channel MOSFET, meaning that it has an n-type (negative) semiconductor between two metal contacts. This MOSFET has a drain-source voltage (VDS) of 650V, a gate-source voltage (VGS) of +/-20V, and a maximum drain current (ID) of 5A. It is designed for use in high-power switching applications, and has high-speed switching capabilities. This device is RoHS certified, meaning it is compliant with all regulations for reducing hazardous substances.
