onsemi announced that NIO Inc. chose the new VE-Trac™ Direct SiC power modules from onsemi for its next-generation electric vehicles (EVs). The silicon carbide (SiC)-based power modules enable long range, high efficiency and fast acceleration for EVs. The VE-Trac Direct SiC is an integrated single side direct cooling (SSDC) power module in a six-pack configuration with a low turn on resistance of 1.7 mohm.

This platform implements the second generation SiC MOSFET technology from onsemi to achieve new levels of performance, efficiency, and quality while sharing a compatible package footprint with its IGBT predecessor. An integrated pin fin baseplate enables direct liquid cooling and easy assembly which allows maximum power output and more efficient thermal dissipation. The VE-Trac offerings, including previously introduced VE-Trac Dual and VE-Trac Direct platforms, are available in silicon-based IGBT and in SiC with various voltages, and for traction inverter power ranging from 100 to 250 kW.

With its standardized mechanical footprints and expanded power ratings, the VE-Trac product family is designed to effortlessly scale EV power outputs, accelerating the adoption of hybrid and battery EVs (BEV). onsemi will showcase its intelligent power and sensing solutions, including VE-Trac platforms, at PCIM Europe 2022 at Messe Nuremberg, Hall 9, Stand 330 from May 10, 2022 to May 12, 2022.
