SiC MOSFET provides ultra-fast switching in power electronics

Littelfuse has introduced its first series of SiC MOSFETs, the latest addition to the company’s growing power semiconductor line. The LSIC1MO120E0080 Series, with a voltage rating of 1200V and ultra-low (80mOhm) on-resistance, is the first organically designed, developed, and manufactured SiC MOSFETs to be released by this partnership. This device is optimized for high-frequency switching applications, providing a combination of ultra-low switching losses and ultra-fast switching speeds that’s unavailable with traditional power transistor solutions. The series has substantially greater energy efficiency, reduced system size/weight, and increased power density in power electronics systems. It also offers superior robustness and exceptional performance, even at high operating temperatures (150C). Typical applications for these new SiC MOSFETs include power conversion systems such as solar inverters, switch mode power supplies, UPS systems, motor drives, high voltage DC/DC converters, battery chargers and induction heating. “Our new SiC MOSFET Series is a critical milestone in our journey to become a leading component supplier in the power semiconductor industry,” said Michael Ketterer, product marketing manager for Power Semiconductors, Electronics Business Unit at Littelfuse. “Our SiC MOSFET application support network is prepared to help customers enhance the performance of their existing designs, as well as assist those developing new power converter products.”
