With on-resistance as low as 17 milliohms and current ratings ranging from 22A to 150A, these devices are optimized for soft-switching resonant-mode power conversion applications. 

The intrinsic fast body diodes HiPerFETs of the MOSFETs display very soft recovery characteristics, minimizing electromagnetic interference (EMI), especially in half or full-bridge switching topologies. With low reverse recovery charge and time, the body diodes can be utilized to make sure that all the energies are removed during high-speed switching to avoid device failure and achieve high efficiency.
