Infineon IMBF170R1K0M1: A 1700V SiC Trench MOSFET for High-Efficiency Power Conversion
The relentless pursuit of higher efficiency, greater power density, and improved reliability in power electronics is driving the widespread adoption of Wide Bandgap (WBG) semiconductors. Among these, Silicon Carbide (SiC) has emerged as a cornerstone technology for high-voltage and high-frequency applications. The Infineon IMBF170R1K0M1 stands as a prime example of this technological evolution, a 1700V SiC trench MOSFET engineered to redefine performance benchmarks in demanding power conversion systems.
This device is a pivotal component for applications operating from intermediate DC link voltages up to 1000V and beyond, which are common in industrial drives, solar inverters, EV charging infrastructure, and UPS systems. Its ultra-high voltage rating of 1700V provides a significant safety margin, enhancing system robustness and longevity by offering superior resilience against voltage spikes and transients. This built-in headroom allows designers to avoid derating concerns and push their systems to operate closer to their theoretical limits.
At the heart of its performance is Infineon's advanced CoolSiC™ trench MOSFET technology. Unlike planar SiC structures, the trench architecture minimizes the cell density and, crucially, the on-state resistance (RDS(on)) for a given die size. The IMBF170R1K0M1 boasts a remarkably low typical RDS(on) of 1000 mΩ, which directly translates to drastically reduced conduction losses. This efficiency gain means less energy is wasted as heat, enabling cooler operation and simplifying thermal management requirements. The resulting potential for smaller heatsinks and enclosures is a direct path to achieving higher power density.
Furthermore, the inherent material properties of SiC allow this MOSFET to operate at significantly higher switching frequencies than its silicon counterparts. The device features low switching losses and a robust, fast body diode that eliminates the need for external anti-parallel diodes in many topologies. This enables the design of smaller, lighter passive components like inductors and capacitors, further contributing to system miniaturization and cost reduction without compromising performance.
The module is offered in the industry-standard TO-247 3-pin package, ensuring both excellent thermal performance and ease of design-in for existing layouts and manufacturing processes. Its high-temperature operational capability ensures reliable performance under strenuous conditions.
