FSB50325A provides low electromagnetic interference (emi) characteristics with optimized switching speed. moreover, since it employs frfet as a power switch, it has much better ruggedness and larger safe operation area (soa) than that of an igbt-based power module or one-chip solution. the package is optimized for the thermal performance and compactness for the use in the built-in motor application and any other application where the assembly space is concerned. FSB50325A is the best solution for the compact inverter providing the energy efficiency, compactness, and low electromagnetic interference.
