Littelfuse launched new 1.2kV SiC Diodes

Littelfuse announced new 1200V Silicon Carbide diodes during PCIM 2017 last week, called GEN2. Littelfuse, which first focus was protection systems, is now fully entered in the power semiconductor world. This news adds to the recent additional investment in Monolith Semiconductor, a Silicon Carbide power devices start-up.

The diodes are the first to be produced using the Monolith Semiconductor partnership. According to Littelfuse, they offer enhanced surge capabilities, with a low leakage. These characteristics add to the usual performances of SiC diodes: higher junction temperature, higher efficiency and power density for boost converters.

Typical applications for these devices are power supplies with a PFC and freewheeling diodes in inverters. The main markets as of now are PV inverters, DC/DC converters, switch mode power supplies, some high-end UPS systems and motor drives.

GEN2 SiC diodes are available at 1200V and at 5 to 10A, in discrete packages.

SiC MOSFETs at 1200V should follow quickly, according to Littelfuse timeline.
