Is ROHM (TSE:6963) Quietly Repositioning Its Power Device Portfolio Around 48V and SiC Leadership? - simplywall.st

ROHM (TSE:6963) has recently launched a new series of 80V power MOSFETs for 48V automotive power systems, signaling a strategic shift in its power device portfolio. These devices feature compact HPLF5... Read original →

ROHM’s aggressive pivot to 48V and SiC power devices is a calculated bet on automotive electrification’s next phase. Its 80V MOSFETs and TSC3PAK packaging aren’t just product launches—they’re forcing upstream wafer suppliers to refine SiC epitaxy yields and pushing downstream OBC designs toward higher power density. While AEC-Q101 compliance ensures reliability, it inflates validation costs at a time of weak industrial demand, deepening near-term losses. Competing against Infineon and STMicroelectronics’ massive SiC capacity expansions, ROHM’s packaging-led differentiation is clever—but without securing SiC wafer self-sufficiency or partnerships with foundries in Taiwan, China by 2027, supply chain fragility looms. Over the next 18 months, if ROHM leverages its early-mover edge to lock in Tier 1 contracts as 48V adoption crosses 25% in Europe and China, it could reverse its 37% valuation discount; otherwise, technical leadership may remain trapped in a cash-burn cycle.
