Where superjunction technology creates system value.
Connect device-level parameters to real converter topologies and the system outcomes engineers care about: efficiency, power density, thermal load and cost.
Power-factor correction
High-voltage SJ MOSFETs are widely used in boost PFC stages where conduction and switching losses both matter.
LLC resonant converters
Low conduction loss and switching behavior can support high-efficiency server, telecom and industrial power supplies.
EV charging
High-voltage power stages can combine silicon SJ, SiC and GaN depending on voltage, power, frequency and cost targets.
AI & data centers
Rising compute power drives demand for higher-efficiency and higher-density power supplies. ROHM's 2026 SJ launches explicitly target AI-server and industrial supplies.
Solar & storage
Inverters and auxiliary power stages benefit from low loss, thermal margin and appropriate blocking-voltage headroom.
Industrial
Motor drives, UPS, welding, HVAC and factory power conversion require different trade-offs across switching frequency and ruggedness.
