IRF520NPBF device package

IRF520NPBF schematic symbol

The electronics revolution started in the true sense with the invention of the transistor. Further advancements in the transistor technology gave birth to the integrated circuits. These transistors and ICs form the backbone of virtually every electronic system present in the world today. With the passage of time many different types of transistors came into existence such as BJTs and MOSFETs. One major field of engineering which sprung out of semiconductors is the power electronics. Power MOSFETs are used as high frequency switches in power electronic converters and inverters. MOSFET stands for metal oxide semiconductor field effect transistor. Power MOSFETs can handle high voltages at high switching speeds. Power MOSFETs are the most widely used semiconductor switches in the world and are widely used in inverters, rectifiers, motor drives and DC choppers. As opposed to BJTs, MOSFETs are voltage controlled devices.
