Littelfuse, Inc., a global leader in circuit protection solutions, has announced the launch of its first family of silicon carbide (SiC) MOSFETs. This marks a significant milestone in Littelfuse’s growing power semiconductor portfolio. In March, the company made a strategic investment in Monolith Semiconductor Inc., a renowned Silicon Carbide Technology Development Company, reinforcing its commitment to becoming a leading player in the power electronics industry.
The LSIC1MO120E0080 series is the first SiC MOSFET developed and produced through this collaboration. Rated at 1200V with ultra-low on-resistance (80mΩ), these devices are optimized for high-frequency switching applications. Their ultra-low switching losses and exceptional speed make them far superior to traditional power transistors, offering improved efficiency and performance in a wide range of industrial and commercial settings.

Compared to traditional silicon-based devices, SiC MOSFETs deliver higher energy efficiency, reduce system size and weight, and increase power density. These advantages are particularly valuable in high-temperature environments, where the devices maintain excellent durability and performance even at 150°C.
The new SiC MOSFETs are ideal for various power conversion systems, including solar inverters, switch-mode power supplies, uninterruptible power supplies (UPS), motor drives, high-voltage DC/DC converters, battery chargers, and induction heating systems. They are designed to meet the demands of next-generation power electronics, enabling more compact, efficient, and reliable designs.
"Expanding our power semiconductor offerings with the introduction of this SiC MOSFET family is a key step in our journey toward becoming a top supplier in the industry," said Michael Ketterer, Power Semiconductor Product Marketing Manager at Littelfuse's Electronics Business Unit. "Our SiC MOSFET Application Support Network helps customers enhance their current designs and supports the development of innovative power conversion products."
Key features of the LSIC1MO120E0080 series include:
- **Ultra-high switching speeds** that boost efficiency and power density.
- **Reduced switching loss**, allowing for higher switching frequencies.
- **High operating temperatures** ensure long-term reliability and performance in demanding environments.
The LSIC1MO120E0080 series is available in a TO-247-3L package, with samples available from authorized Littelfuse distributors worldwide. For more information or to locate an authorized dealer, visit [littelfuse.com](http://www.littelfuse.com).
