The FCAS50SN60 is the world’s first Smart Power Module (SPM) designed especially for driving single-phase switched reluctance motors. The 50 A-rated FCAS50SN60 integrates a high-voltage IC and low-voltage IC, IGBTs, fast recovery diodes, and a thermistor in an ultra-compact (44 mm × 26.8 mm) Mini-DIP package. The package features direct bonded copper technology that significantly increases thermal performance. Compared to typical discrete solutions, the FCAS50SN60 reduces power circuit space by up to 40%, enabling designers to incorporate the controller into the SRM assembly.

The UL-certified device provides an optocoupler-less, single-supply IGBT gate driving capability that further reduces overall system size. Its integrated under-voltage lockout and short-circuit protection ensures excellent reliability. The FCAS50SN60’s optimized switching speed meets EMI requirements. In addition to saving space, the SPM’s Mini-DIP package with innovative DBC technology provides extremely low thermal resistance. FCAS50SN60s cost $30 each in 100-piece quantities.
