It uses advanced HEXFET processing technology to achieve low on-resistance and fast switching in a cost-effective TO-220AB package. The 100V rating provides adequate margin for 48V battery systems and 24V industrial supplies. The device is repetitive avalanche rated for ruggedness in unclamped inductive switching applications. Its combination of moderate voltage, high current, and low on-resistance makes it one of the most popular power MOSFETs for motor control and power conversion.","working_principle":"The IRF540N uses a vertical DMOS structure with planar stripe cell geometry. When VGS exceeds the threshold voltage (2-4V), an inversion layer forms under the gate oxide creating a conductive N-type channel between drain and source. At VGS=10V, the channel is fully enhanced with RDS(on) of 44mOhm. The vertical current flow from drain (back of die) through the channel to source (top of die) maximizes current handling. The built-in body diode provides a freewheeling path for inductive loads. The gate charge of 71nC determines the gate drive power needed for a given switching frequency.","pin_description":"
