• Nexperia and KYOCERA AVX are collaborating to produce a 650 V silicon carbide rectifier module for high-frequency power applications.• The new module aims to maximize power density, reduce board space, lower system cost, and optimize thermal performance.The module is designed specifically for 3 kW to 11 kW power stack designs in EVSEs and OBCs.

The new SiC rectifier module addresses the need for space-saving and weight reduction. Its compact design maximizes power density, minimizing required board space and lowering system cost. Thermal performance is enhanced with a combination of top-side cooling (TSC) and an integrated negative temperature coefficient (NTC) sensor. These sensors monitor device temperature and provides real-time feedback for device or system-level prognosis/diagnosis. The modul is qualified to operate at a junction temperature up to 175 °C.

Katrin Feurle, Senior Director of the Product Group SiC at Nexperia, stated, “This collaboration between Nexperia and KYOCERA AVX combines cutting-edge silicon carbide semiconductors with state-of-the-art module packaging and will allow Nexperia to better serve the market demand for power electronic products which offer exceptionally high levels of power density.” She also noted that this release marks the beginning of a long-term SiC partnership between the two companies.

Thomas Rinschede, Deputy Vice President Sensing and Control Division at KYOCERA AVX Components Sensing and Control Division, added “We are delighted to further extend our successful partnership with Nexperia into the production of silicon carbide modules for power electronics applications. Nexperia’s manufacturing expertise combined with KYOCERA module know-how make a compelling offering for customers looking to achieve higher power densities using wide bandgap semiconductor technology.”

Nexperia anticipates the availability of sample SiC rectifier modules in the first quarter of 2024.
