Ultra Junction MOSFETs

IXYS Ultra Junction MOSFETs feature low R_DS(on) and low Q_g in low inductance industry standard packages. These devices enable high power density, easy mounting, and space-saving opportunities. IXYS Ultra Junction MOSFETs are ideal solutions in SMPS, DC-DC converters, PFC circuits, AC and DC motor drives, and robotics/servo controls.
