Navitas Gen-3 Fast SiC MOSFETs in D2PAK-7L and TOLL surface-mount packages
Gallium nitride (GaN) power IC and silicon carbide (SiC) technology firm Navitas Semiconductor Corp of Torrance, CA, USA has released 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 what is claimed to be 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 that is reckoned to be up to 3x longer than alternative SiC products, for high-stress EV environments.
Gen-3 Fast MOSFETs are optimized for the fastest switching speed and 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 what is claimed to be leading-edge OBC system solutions up to 22kW with 3.5kW/liter power density, and over 95.5% efficiency.
400V-rated EV battery architectures are served by the new 650V Gen-3 Fast MOSFETs featuring RDS(ON) ratings from 20mΩ to 55mΩ. The 1200V ranges from 18mΩ to 135mΩ and is optimized for 800V systems.
Both 650V and 1200V ranges are AEC Q101-qualified in the traditional SMT D2PAK-7L (TO-263-7) package. For 400V EVs, the 650V-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 2nH ensures excellent fast-switching performance and lowest dynamic package losses.
The automotive-qualified 650V and 1200V G3F SiC MOSFET family in D2PAK-7L and TOLL surface-mount packages are released and available immediately for purchase.
