The IRFB4110PBF is a 100V N-channel enhancement mode power MOSFET from Infineon Technologies featuring advanced HEXFET technology. With a continuous drain current of 120A and an ultra-low maximum on-resistance of 4.5mΩ at VGS=10V, this device delivers exceptional conduction performance in a compact TO-220AB package. The IRFB4110PBF is specifically optimized for high efficiency synchronous rectification and high speed power switching applications, featuring improved gate, avalanche, and dynamic dv/dt ruggedness, fully characterized capacitance and avalanche SOA, and enhanced body diode dV/dt and dI/dt capability. With a power dissipation rating of 330W and an operating junction temperature up to 175°C, this MOSFET is ideal for demanding applications including switch mode power supplies, DC-DC converters, UPS systems, battery management, and motor control where high efficiency and reliability are paramount.

The IRFB4110PBF operates as an N-channel enhancement mode MOSFET where a positive gate-source voltage above the threshold (2-4V) induces a conductive channel in the P-type body region, allowing electron flow from source to drain. At VGS=10V, the device is fully enhanced, providing its minimum on-resistance of 4.5mΩ maximum, which is critical for minimizing conduction losses at high current levels. The HEXFET technology with optimized cell geometry achieves this low resistance while maintaining the 100V blocking voltage through carefully designed drift region doping and termination structures. With VGS=0V, the MOSFET blocks up to 100V across the drain-source junction with very low leakage current. The intrinsic body diode provides reverse conduction capability, making the device suitable for synchronous rectifier applications where it must carry inductor current during the off-cycle. The device is fully avalanche rated, meaning it can safely dissipate energy during unclamped inductive switching events, providing enhanced reliability in real-world power supply and motor drive applications.
