PCIM 2026: Accepting local component deficits for system-level benefits - digitimes

In power electronics engineering, silicon carbide (SiC) companies are competing to achieve the absolute lowest thermal resistance (Rth), with the mindset that lower heat signature equates a superior s... Read original →

The shift from minimizing thermal resistance at all costs to system-level optimization in SiC power devices triggers cascading effects: substrate suppliers must redefine defect tolerance, while module assemblers accelerate heterogeneous integration to offset localized performance trade-offs. Regulatory pressure—particularly the EU’s upcoming Green Electronics Act mandating lifecycle efficiency—exposes the hidden carbon and cost penalties of over-optimizing single metrics. Strategically, Wolfspeed may leverage vertical integration, whereas Infineon and STMicroelectronics could pivot to open IP ecosystems to lock in customers. Over the next 12–24 months, a new evaluation paradigm—'suboptimal components, optimal systems'—will emerge. IDM players in Taiwan, China and mainland China risk missing this architectural inflection point if they remain fixated on parametric one-upmanship.
