Navitas Qualifies Leading-edge Gen-3 Fast SiC to Auto-grade (Q101)
Next-gen silicon carbide (SiC) power semis drive innovation in 400 and 800 V EV architectures.
Navitas Semiconductor, the industry leader in next-generation GaNFast™ gallium nitride (GaN) and GeneSiC™ silicon carbide (SiC) power semiconductors, today announced the release of a portfolio of third-generation automotive-qualified SiC MOSFETs in D2PAK-7L (TO-263-7) and TOLL (TO-Leadless) surface-mount (SMT) packages.
Navitas’ proprietary ‘trench-assisted planar’ technology provides world-leading performance over temperature and delivers high-speed, cool-running operation for electric vehicle (EV) charging, traction, and DC-DC conversion. With case temperatures up to 25°C lower than conventional devices, Gen-3 Fast SiC offers an operating life up to 3x longer than alternative SiC products, for high-stress EV environments.
Gen-3 Fast MOSFETs are optimized for the fastest switching speed, highest efficiency, and support increased power density in EV applications such as AC compressors, cabin heaters, DC-DC converters, and on-board chargers (OBCs). Navitas’ dedicated EV Design Center has demonstrated leading edge OBC system solutions up to 22 kW with 3.5 kW/liter power density, and over 95.5% efficiency.
400 V-rated EV battery architectures are served by the new 650 V Gen-3 Fast MOSFETs featuring RDS(ON) ratings from 20 to 55 mΩ. The 1,200 V ranges from 18 to 135 mΩ and is optimized for 800 V systems.
Both 650 and 1,200 V ranges are AEC Q101-qualified in the traditional SMT D2PAK-7L (TO-263-7) package. For 400 V EVs, the 650 V-rated, surface-mount TOLL package offers a 9% reduction in junction-to-case thermal resistance (RTH,J-C), 30% smaller PCB footprint, 50% lower height, and 60% smaller size than the D2PAK-7L. This enables very high-power density solutions, while minimal package inductance of only 2 nH ensures excellent fast-switching performance and lowest dynamic package losses.
