Introduction The power electronics industry stands at a crucial inflection point. As industrial applications demand higher efficiency, greater power density, and reduced costs, traditional silicon- based solutions increasingly fall short. This comprehensive guide explores how Infineon's CoolSiC™ technology portfolio directly addresses these issues, offering engineers the tools they need to develop next-generation power systems. Today's industrial applications — from solar inverters and energy storage systems to EV charging infrastructure — are boosting DC link voltages to unprecedented levels, reaching up to 1500V. This trend signals a fundamental change: higher voltages enable greater power ratings with significantly reduced losses, but they also require semiconductors capable of reliably handling these extreme conditions. Infineon's CoolSiC™ technology portfolio provides 2000V SiC devices with an impressive RDS(on) range, from 100 milliohms down to just 7 milliohms. Built on an innovative trench design, these devices deliver exceptional gate oxide reliability, immunity to parasitic turn-on, and the ability to operate at 0V gate-source voltage, greatly simplifying system design. This guide explores four key areas to accelerate your power design development: Technology Evolution: Discover the strategic step from Generation 1 to Generation 2, where significant improvements in switching efficiency, thermal management, and package design lead to measurable performance gains. Enhanced Performance: Learn about our innovative .XT interconnection technology, which achieves 30% better thermal resistance while providing superior electrical performance. Smart Packaging Solutions: Explore the game- changing topside-cooled Q-DPAK design that eliminates the traditional trade-off between thermal performance and manufacturing efficiency. Design Support: Access comprehensive development resources, including advanced simulation tools and validated reference designs that help streamline your project timeline. Whether you're designing solar inverters, energy storage systems, or industrial drives, this guide demonstrates how CoolSiC™ technology can transform your approach to power electronics—providing the performance, reliability, and design flexibility your applications demand. 3 Enabling Compact, Efficient Designs with High Voltage CoolSiC™ Discretes
