BUK9J0R9-40H – A Super Junction MOSFET with Low On-State Resistance

A MOSFET known as a metal-oxide-semiconductor-field-effect transistor is a special type of field-effect transistor which has an insulated gate where in this case the voltage determines the conductivity of the device. Just like conventional transistors, they are also used for switching and amplifying signals. MOSFETs are now more commonly used in digital and analog circuits
