5. Mitsubishi Electric

Mitsubishi Electric brings decades of power-electronics experience to high-power IGBT modules and power systems for traction, industrial drives and renewable installations. As a diversified industrial group formed in 1921, Mitsubishi Electric leverages in-house system experience (inverters, motors and railway traction) to optimize module portfolios for heavy-duty, long-lifecycle applications that demand strict reliability and availability. Their modules are typically chosen where mature supply chains, local engineering support and system-level experience are decisive.

6. Toshiba

Toshiba’s long history in electronics supports a robust lineup of power devices and modules, including IGBT modules, MOSFETs and discrete SiC diodes for industrial and automotive applications. With corporate roots reaching back to 1939, Toshiba combines materials, device and packaging expertise to supply both end-users and OEM subsystem makers. Toshiba’s modules are often chosen for legacy industrial platforms and for applications where integration with other Toshiba subsystems (storage, control systems) is valuable.

7. Semikron

Semikron is a German specialist long-known for power-modules (SEMiX, SEMITOP, SEMITRANS families) and customer-configurable stacks for converters and motor drives. Founded in 1951 and recently operating as Semikron-Danfoss after a strategic combination, the company focuses intensely on module packaging, thermal management and scalable product lines for industrial and renewable-energy converters. Semikron remains a go-to supplier where custom module topologies, high-current packaging and system integration support are required.

8. Fuji Electric

Fuji Electric supplies IGBT modules, SiC modules and intelligent power modules with an emphasis on industrial drives, renewable inverters and traction systems. As a legacy Japanese maker of power semiconductors, Fuji provides extensive product lines (including all-SiC modules) and parametric design tools for industrial customers. Their new product launches (e.g., HPnC series) demonstrate continued investment in high-voltage and high-power module platforms for renewables and heavy industrial use.

9. ROHM Semiconductor

ROHM offers IGBTs, MOSFETs, IPMs and compact power modules focused on efficiency and thermal performance. Founded in 1958, ROHM combines device R&D with module integration (IPMs for motor control and power-supply modules) that are popular in white goods, HVAC, EV auxiliary systems and industrial drives. Recent product news highlights advanced 1200 V IGBTs tailored to automotive and industrial markets, underscoring ROHM’s push into higher-voltage and automotive-grade offerings.

10. Wolfspeed

Wolfspeed (Cree/Wolfspeed lineage) is a pure-play SiC leader focused on silicon-carbide devices, power dies and SiC-optimized modules for automotive, charging and utility-scale inverters. Wolfspeed’s HM and YM module families target high-voltage, high-reliability applications with SiC-optimized packaging that enables high junction temperatures and power density. For designs targeting maximum efficiency and reduced thermal mass, Wolfspeed’s SiC modules are an increasingly common choice.
