The IRFZ48VSPBF is a N-channel MOSFET transistor manufactured by Infineon Technologies. It is commonly used for low-side switching and load-switching applications such as motor control, DC/DC conversion, switching regulators, and general power applications. This component has an intrinsic body diode for freewheeling and ESD protection, is isolated from the gate, and has built-in protection from accidental overvoltage. It has an RDS(ON) as low as 0.37?, a drain source voltage (VDS) of up to 55 V, and a maximum current of 48 A. It is shipped in a TO-220AB package to ensure reliable mounting, cooling, and electrical connections.
