ROHM's SiC MOSFET Adopted in BBU for AI Servers as HVDC Architectures Advance - TradingView

ROHM's 750V SiC MOSFET has been adopted in Battery Backup Units (BBUs) for AI servers, reflecting the industry's shift toward high-voltage direct current (HVDC) architectures driven by the rapid growt... Read original →

ROHM’s 750V SiC MOSFET adoption in AI server BBUs signals HVDC architecture’s shift from niche to norm. Technically, this forces upstream upgrades in capacitors, gate drivers, and thermal solutions while accelerating 800V DC bus standardization. Regulatory pressure—like the EU’s Ecodesign Directive—will raise entry barriers for non-SiC power supplies, squeezing smaller vendors out of premium segments. In response, Infineon and Wolfspeed may fast-track automotive-grade SiC devices into data centers, leveraging existing ruggedness. Meanwhile, Taiwan, China-based foundries like TSMC and Win Semiconductors risk losing custom orders to vertically integrated rivals. Within 18 months, HVDC-integrated BBUs will become default in AI racks, pushing SiC penetration from under 15% to over 40%, cementing material performance as the new competitive moat.
