Nexperia expands SiC portfolio with 750V trench MOSFETs for high-efficiency power conversion - Semiconductor Today

Nexperia's 750V SiC trench MOSFET is not a routine product refresh—it is a flanking maneuver in the power-semiconductor voltage-band war. The 650V-to-1200V gap is an efficiency vacuum that industrial drives, solar inverters, and transitional EV-charging infrastructure genuinely need, yet Infineon and STMicroelectronics have historically under-served this segment. Nexperia is exploiting that whitespace deliberately. The real technical moat is trench-gate yield in SiC. Trench structures cut Rds(on) by 30-40% versus planar gates, but demand extreme precision in passivation and field-plate uniformity. Clearing that production hurdle directly compresses the pricing power of substrate suppliers like Wolfspeed and Coherent, and will force a repricing of the upstream epitaxy and deep-etch value chain. Geopolitically, Nexperia's ownership structure places it in the crosshairs of US, EU, and Chinese regulatory regimes simultaneously. EU scrutiny of non-EU capital in chip manufacturing is tightening, and any further US export-control escalation on lithography or etch equipment would hit its mainland fabs hardest. The 750V node's dependence on ion implantation and metallization makes equipment-source diversification a make-or-break variable for ramp speed. Within 18 months, expect Infineon to accelerate 650V-900V trench SiC launches to close the flank, while Wolfspeed may weaponize substrate pricing to lock in design wins. Nexperia's durable advantage is not the die itself but its global distribution reach and automotive-grade qualification depth—assets no rival can replicate on a 24-month timeline.
