Littelfuse announces SiC MOSFET

Oct. 7, 2017

Chicago, IL. Littelfuse Inc. has introduced its first series of silicon-carbide (SiC) MOSFETs, the latest addition to the company’s power-semiconductor line. In March, Littelfuse took an incremental step towards establishing itself in the power-semiconductor industry through a majority investment in the SiC technology-development company Monolith Semiconductor Inc. The LSIC1MO120E0080 Series, with a voltage rating of 1,200 V and ultralow (80-mΩ) on-resistance, is the first organically designed, developed, and manufactured SiC MOSFET to be released by this partnership. This device is optimized for high-frequency switching applications, providing a combination of ultralow switching losses and ultrafast switching speeds that’s unavailable with traditional power transistor solutions.


When compared with silicon devices that have the same rating, the SiC MOSFET Series enables greater energy efficiency, reduced system size/weight, and increased power density in power electronics systems, the company said, adding that it also offers robustness and performance even at high operating temperatures (150°C).

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 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.”

The LSIC1MO120E0080 Series SiC MOSFET is available in TO-247-3L packaging and provided in tubes in quantities of 450. Sample requests may be placed through authorized Littelfuse distributors worldwide. For more information visit the LSIC1MO120E0080 Series SiC MOSFET product page.
