SiC / GaN / IGBT vendor dynamics, supply chain, and procurement risk
Comparing the Competitiveness of Power Module Tier 1 Suppliers
This article benchmarks six leading power module suppliers — Infineon, onsemi, STMicro, Mitsubishi Electric, Fuji Electric, and Rohm — across four dimensions: product lineup, SiC capability, supply capacity, and price competitiveness. The findings are intended as a reference for procurement source selection.
SiC Module Packaging Technology Trends — How Next-Generation Packages Are Redefining Thermal Design
Performance limitations in SiC power modules are often attributable to packaging rather than the devices themselves. The shift from gel encapsulation to epoxy and ceramic encapsulation, and the adoption of double-sided cooling structures, are packaging and assembly technology trends that will determine the competitiveness of next-generation SiC systems.
EV Power Semiconductor Application Selection Matrix
The cost of SiC power modules per inverter is 2 to 3 times higher than traditional Si-based modules, yet EV manufacturers are accelerating their transition to SiC because the increased efficiency and reduced size of the overall system offset this higher component cost; however, it is not simply a matter of "using SiC," as EV power conversion systems are divided into multiple applications, each with its own...
SiC Modules vs. Discrete Components: Selection Criteria
Once the decision to use SiC is made in the early stages of inverter design, the next question is whether to opt for modules or discrete components, a choice that, while appearing to be merely an implementation form, fundamentally impacts system performance, board area, protection circuit design, and procurement flexibility.
STMicroelectronics Ampere SiC Power Modules for EV 2026
STMicroelectronics and Ampere (a distinct EV powertrain design company, not the Arm-based server design firm formerly part of Oracle) are reportedly collaborating on SiC power modules for next-generation EV traction inverters, targeting commercialization in 2026; the announcement's core is simple, yet it implies a significant strategic shift.
