FSB50250AB: Smart Power Module (SPM®)

FSB50250AB is a tiny smart power module (SPM®) based on FRFET technology as a compact inverter solution for small power motor drive applications such as fan motors and water suppliers. It is composed of 6 fast-recovery MOSFET (FRFET), and 3 half-bridge HVICs for FRFET gate driving. FSB50250AB 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.

FSB50250AB is the best solution for the compact inverter providing the energy efficiency, compactness, and low electromagnetic interference.
