Wolfspeed announced that its 300 mm silicon carbide technology platform could become a key materials foundation for advanced heterogeneous packaging used in AI and high-performance computing systems by the end of the decade.
The initiative builds on the company’s January 2026 milestone of producing a single-crystal 300 mm SiC wafer. Wolfspeed is now working with partners across the AI ecosystem to evaluate how large-diameter silicon carbide substrates could help address emerging performance limitations in next-generation semiconductor packaging.
As AI workloads increase, semiconductor packages are growing in size, power density, and integration complexity. These trends are pushing conventional materials used in advanced packaging toward their thermal, mechanical, and electrical limits. Wolfspeed believes silicon carbide can help address these challenges because of its high thermal conductivity, mechanical robustness, and favorable electrical characteristics.
Using a 300 mm SiC wafer format also aligns with the existing semiconductor manufacturing infrastructure used for advanced silicon devices. This compatibility allows potential integration with current wafer-level packaging processes and fabrication tools while supporting scalable high-volume manufacturing.
The company is collaborating with foundries, outsourced semiconductor assembly and test providers, system architects, and research institutions to study the feasibility of silicon carbide interposers and related packaging components. The program aims to evaluate performance benefits, reliability, and integration pathways for hybrid silicon–silicon carbide packaging architectures.
According to Wolfspeed, the larger 300 mm wafer format could enable fabrication of larger interposers and heat spreaders required for increasingly large and complex semiconductor packages used in AI and HPC systems. The approach is intended to support the industry’s transition toward higher integration levels while maintaining manufacturability and ecosystem compatibility.

Micro Commercial Components (MCC) has introduced the SICWT40120G6M, a 1200 V silicon carbide Schottky diode designed to address switching losses, thermal stress, and reliability challenges in high-voltage, high-frequency power conversion systems.
Traditional rectifier solutions can increase power dissipation, require larger cooling solutions, and limit achievable power density, particularly in high-current and high-temperature environments. The new device is intended to improve efficiency and reliability in these demanding operating conditions.
The SICWT40120G6M is built on merged PiN Schottky (MPS) technology, enabling zero reverse recovery behavior along with low forward voltage and very low leakage current. These characteristics significantly reduce switching and conduction losses in high-frequency power conversion applications.
The diode supports high continuous and surge current capability and operates across a wide junction temperature range from −55°C to +175°C. A positive temperature coefficient helps maintain stable operation and reduces the risk of thermal runaway in high-power systems.
The device is packaged in a TO-247AD package designed for strong thermal performance, supporting efficient heat dissipation and enabling more compact and reliable system designs.
According to MCC, the new SiC diode targets applications including industrial power conversion, transportation systems, and EV charging infrastructure, where high efficiency, thermal robustness, and compact design are critical requirements.

Navitas Semiconductor and École Polytechnique Fédérale de Lausanne announced the exhibition of a 250 kW solid-state transformer (SST) solution at APEC 2026 in San Antonio, Texas.
The SST platform was developed by EPFL’s Power Electronics Laboratory and is designed to support the grid architecture required by next-generation data centers. The system replaces bulky low-frequency transformers while improving end-to-end efficiency. The design uses a single-stage, modularized bridge rectifier SST topology to convert 3.3 kV AC to 800 V DC at 250 kW power, enabling improved performance and modularity for modern data center infrastructure.
The demonstrator is built using Navitas GeneSiC ultra-high voltage 3300 V and high-voltage 1200 V silicon carbide trench-assisted planar MOSFETs and modules. The project is part of the Power Electronics Laboratory’s HeatingBits initiative, which aims to deploy and evaluate advanced power technologies inside EPFL’s operational data center.
According to Navitas, the collaboration demonstrates how medium-voltage power conversion can address the energy and thermal challenges associated with AI data centers. By combining high-voltage silicon carbide devices with a single-stage solid-state transformer architecture and advanced real-time control, the system enables scalable 800 V DC power distribution designed to improve efficiency from the grid to server racks while also supporting potential heat reuse.
