NEDITEK Unveils Groundbreaking 750V Automotive-Grade SiC MOSFET Series, Powering Next-Gen Vehicle Power Systems

NEDI Technology Co., Ltd. (NEDITEK) today announced the official launch of its new 750V automotive-grade Silicon Carbide (SiC) MOSFET product series. The initial release features three key on-resistance (RDS(on)) ratings: 15mΩ, 23mΩ, and 40mΩ. The series is offered in traditional industrial packages including TO-247-4L and TO263-7, as well as two innovative packages optimized for high-voltage automotive applications: QDPAK and HU2PAK. This comprehensive lineup aims to meet the stringent demands for high efficiency, high power density, and superior reliability in new energy vehicle (NEV) on-board chargers (OBC) and DC-DC converters.

The new products are based on NEDITEK’s advanced third-generation SiC planar technology, achieving an industry-leading balance between conduction loss, switching performance, and reliability. Notably, the QDPAK and HU2PAK packages, developed specifically for 400V and 500V bus voltage platforms, represent the company’s forward-looking strategy in system-level solutions. These packages not only feature a smaller form factor, enabling more compact power design for customers, but also introduce a key innovation: ​top-side cooling​ capability. This allows heat to be dissipated efficiently directly to the system heatsink, significantly optimizing thermal management and offering substantial advantages in the high-temperature, high-power automotive environment.

“As the rapid adoption of 800V high-voltage fast-charging platforms and increasingly stringent demands for space and efficiency in vehicle power systems progress, the market urgently needs SiC solutions with superior performance and better thermal management,” said Mr. Yang, General Manager of the Power Device Product Line at NEDITEK. “Our new 750V SiC MOSFET series, especially the innovative QDPAK and HU2PAK packages, are designed precisely for this purpose. They can help customers push the efficiency of OBCs and DC-DCs to new heights while reducing system size and cost, accelerating the evolution of new energy vehicles.”

The product series has passed AEC-Q101 automotive-grade reliability certification and is currently undergoing joint testing and design-in processes with several leading global Tier 1 suppliers and OEMs. Early test data indicates that in typical OBC application scenarios, solutions utilizing these devices can achieve over 1.5% higher system efficiency compared to existing silicon-based solutions, or deliver up to a 30% increase in power density at the same efficiency level.
