Industry Analysis
ROHM’s PCIM 2026 showcase signals a strategic pivot from discrete SiC performance to system-level integration, pressuring upstream substrate makers to boost 6-inch wafer yields and accelerating 800V adoption in EV drivetrains. The EU’s Critical Raw Materials Act—mandating 50% domestic wide-bandgap semiconductor capacity by 2030—exposes ROHM’s reliance on Japanese and Taiwan, China fabs to rising compliance costs. As Infineon and STMicro ramp vertical integration, ROHM’s modular-plus-IP licensing approach may catalyze a broader shift among Japanese peers toward asset-light tech monetization. Over the next 18 months, surging demand from AI server PSUs and solar inverters will make SiC/GaN hybrid topologies standard in industrial power supplies; securing European Tier 1 partnerships now could lock in carbon-border-adjustment advantages ahead of rivals.
