With 11 mOhm maximum on-resistance and 104 A continuous drain current rating, this device is ideal for low-frequency switching applications that demand high performance and ruggedness. The StrongIRFET family provides a softer body diode compared to previous generations, reducing reverse recovery losses. Packaged in the industry-standard TO-220, it serves as a drop-in replacement for existing designs.","working_principle":"The IRFB4115PBF operates as a voltage-controlled switch. When a positive gate-source voltage exceeding the threshold is applied, an inversion layer forms in the N-channel, allowing current to flow from drain to source. The low RDS(on) of 11 mOhm minimizes conduction losses at high currents. The device features an integral body diode that conducts when the drain-source voltage is reversed, providing a freewheeling path for inductive loads. The trench MOSFET technology enables low gate charge for efficient switching.","pin_description":"
