Navitas launches isolated package for high-voltage SiC MOSFETs By Investing.com - Investing.com South Africa

Navitas Semiconductor has launched the UHV-TO-247-4-ISO package tailored for high-voltage silicon carbide (SiC) MOSFETs. The new design offers over 12mm creepage and more than 6000V integrated isolati... Read original →

Navitas’s isolated UHV-TO-247-4 package isn’t just a packaging upgrade—it directly tackles system-level integration bottlenecks in high-voltage SiC. By integrating aluminum nitride substrates and reflow-compatible thermal pads, it slashes thermal resistance by 60%, forcing upstream wafer suppliers to enhance crystal quality and downstream designers to rethink thermal architectures in grid-tied converters and solid-state transformers. Amid U.S.-EU efforts to onshore wide-bandgap supply chains, this move boosts Navitas’s compliance posture in AI infrastructure and renewables, yet its fabless model remains a supply chain vulnerability. Facing Wolfspeed and Infineon’s dominance above 3300V, Navitas leverages packaging innovation for asymmetric competition—likely triggering rivals to accelerate vertical integration or ecosystem partnerships. Over the next 18 months, as NVIDIA’s AI factories drive demand for 800V DC buses, high-isolation, low-thermal-resistance SiC modules will become de facto standards. If Navitas locks in NVIDIA co-design wins and manages yield ramp effectively, it could carve a defensible niche in the premium power semiconductor segment.
