FSB50325AT: Motion SPM® 5 Series

FSB50325AT is an advanced Motion SPM® 5 series based on fast-recovery MOSFET (FRFET®) technology as a compact inverter solution for small power motor drive applications such as fans and pumps. FSB50325AT contains six FRFET MOSFETs, three half-bridge gate driver HVICs with temperature sensing, and three bootstrap diodes in a compact package fully isolated and optimized for thermal performance. FSB50325AT features low electromagnetic interference (EMI) characteristics through optimizing switching speed and reducing parasitic inductance. Since FSB50325AT employs MOSFETs as power switches, it provides much more ruggedness and larger safe operating area (SOA) than IGBT-based power modules. FSB50325AT is the right solution for compact and reliable inverter designs where the assembly space is constrained.
