IXYS Corporation has announced the introduction of a new addition to its 4.5kV power semiconductor family, designed to support high-voltage industrial power conversion and advanced IGBT module applications. Developed by IXYS UK, the new device is a high-performance fast recovery diode (FRD) optimized for use alongside the company's extensive range of press-pack IGBT modules.
The new component features a rated operating current of 460A and incorporates advanced semiconductor processing and assembly technologies. Compared to older floating silicon designs, the updated structure offers improved thermal stability, enhanced mechanical robustness, and superior switching performance. The device is capable of supporting extremely high current change rates, exceeding 2kA per microsecond, while maintaining soft recovery characteristics and low switching losses.
Packaged in a fully hermetic ceramic housing with copper electrodes, the diode is designed for high-reliability power electronics environments. Its construction allows compatibility with series-connected press-pack IGBT modules used in demanding industrial applications, including high-voltage converters, power transmission systems, and railway traction equipment.
The new E0460QC45E diode is optimized for use with IXYS UK's 4500V IGBT modules and can serve as an antiparallel diode, neutral-point clamp diode, or snubber diode in multilevel converter topologies. These applications are commonly found in renewable energy systems, industrial motor drives, HVDC power transmission, and large-scale power conversion equipment.
As demand continues to grow for high-voltage IGBT modules, power semiconductors, railway traction systems, renewable energy converters, and industrial power electronics, advanced devices such as the E0460QC45E help improve efficiency, reliability, and overall system performance. This latest addition further strengthens IXYS UK's portfolio of high-power semiconductor solutions for modern energy and industrial applications.
