Power Electronics Companies Matrix by Mordor Intelligence
Our comprehensive proprietary performance metrics of key Power Electronics players beyond traditional revenue and ranking measures
The MI Matrix can look different from simple revenue rankings because it weighs what buyers experience day to day. Reach across regions, depth of qualified power device families, and evidence of recent platform rollouts often change who looks strongest. Asset readiness also matters, especially when new wafer sizes, advanced packaging, and thermal limits decide real delivery capability. Executives also tend to ask which suppliers can support 800 V vehicle systems and high density data center power trains with fewer conversion stages. They also ask which vendors can keep silicon carbide and gallium nitride supply stable while standards and cybersecurity requirements tighten. This MI Matrix by Mordor Intelligence is better for supplier and competitor evaluation than revenue tables alone because it ties position to observable footprint, operating readiness, and product momentum.

Comprehensive positioning breakdown
Infineon Technologies AG
Execution discipline is visible in the 200 mm silicon carbide roadmap, with customer releases tied to Villach in early 2025. Infineon, a leading player, benefits when vehicle charging and renewable buildouts demand higher efficiency switching. Packaging and yield learning become the next risk as volumes rise, since cost curves decide design wins. The company introduced a new silicon carbide MOSFET generation for demanding conversion use cases in 2024. If export controls tighten further, it can re route capacity across its multi site footprint, but qualification timing becomes the constraint.
Mitsubishi Electric Corporation
Vehicle inverter focus strengthened in 2024 through new module sampling tied to xEV needs. Investment includes a major OEM putting funds into module assembly and inspection capacity in Japan, with a new facility planned to start operations in October 2026. Supply stability improves when 12 inch silicon wafer processing feeds module assembly at scale. A realistic upside case comes from grid scale power conversion collaborations, including work announced with ITRI in 2025. The main risk is capex timing if vehicle demand remains uneven through 2026.
ON Semiconductor Corporation
Capacity commitments became more concrete when the Bucheon silicon carbide expansion was completed in 2023, with a stated path to 200 mm conversion. ON Semiconductor, a top player, gains leverage when customers want vertically supported supply assurance, including long duration agreements tied to electrified drivetrains. In 2025 the firm extended silicon carbide into intelligent power modules aimed at inverter motor drives used in data centers and industrial equipment. If GaN adoption accelerates faster than expected, the 2025 GaN collaboration approach could broaden supply options, but execution risk sits with process transfer.
STMicroelectronics N.V.
Footprint reshaping matters because it determines who can qualify 200 mm wide bandgap supply at steady yields. STMicroelectronics, a leading producer, is progressing a dedicated silicon carbide campus in Catania, with 200 mm wafer production targeted for Q4 2025. That timing aligns with tighter efficiency rules for chargers, inverters, and server power, which favors higher switching performance. Faster adoption of higher voltage architectures in vehicles and data centers is a plausible upside that could pull advanced modules forward. The key operational risk is ramp complexity across older and newer wafer sizes while maintaining automotive grade qualification at scale.
Texas Instruments Inc.
US manufacturing scale is becoming a strategic differentiator as buyers prioritize continuity and verified origin. Texas Instruments, a major supplier, began production at its Sherman, Texas 300 mm facility in December 2025, with stated plans to ramp output with demand. That capacity supports power management IC continuity for vehicles, factories, and medical devices where redesign costs are high. If trade restrictions widen, domestic capacity can become a purchasing advantage, though workforce and tool supply still constrain speed. The main risk is that older fabs are resized too fast, creating short term tightness for mature power nodes.
ROHM Co., Ltd.
Automotive traction and charging momentum is clearer when parts are shipping inside named vehicle platforms. ROHM, a top manufacturer, benefits from long duration capacity partnerships that reduce program risk for inverter builders. In 2025 the company moved to reduce package switching friction through a packaging collaboration with Infineon, which supports second source confidence for engineers. If vehicle makers pivot further toward 800 V systems, the opportunity grows, but supply chain bottlenecks in wafers and advanced packaging can still cap near term output.
Frequently Asked Questions
What matters most when selecting a silicon carbide power device partner for EV inverters?
Prioritize qualified device families, stable wafer sourcing, and proven packaging thermal performance. Ask for lifetime test data under your switching profile and cooling limits.
When should a design team choose GaN over silicon carbide for power conversion?
GaN usually fits higher frequency, lower voltage stages where size and fast switching dominate. Silicon carbide is typically favored for higher voltage and higher power stages where ruggedness leads.
How can buyers reduce supply risk for 200 mm wide bandgap transitions?
Qualify two package compatible options and confirm the supplier has a clear transfer plan across wafer sizes. Contract for allocation rules and validate lead time behavior during demand spikes.
What are the most common qualification pitfalls for high voltage power modules?
Thermal cycling and partial discharge performance often fail late if the mechanical stack up is not stable. Gate driver interaction can also create voltage overshoot that invalidates reliability assumptions.
What capabilities should a supplier show for grid connected converters and storage systems?
Look for high voltage module options, strong application engineering, and clear compliance support for grid codes. Serviceability and field diagnostics also matter for uptime.
How should aerospace and defense buyers evaluate rugged power electronics suppliers?
Focus on traceability, documented change control, and proven performance across temperature extremes. Confirm long term support policies since redesign cycles are slow and expensive.
Methodology
Research approach and analytical framework
Used company investor materials, filings, and official press rooms as primary evidence. Private firm signals used site footprint, product releases, and named partnerships. Indicators were triangulated when direct segment data was not available. Scoring favored evidence inside the defined scope only.
Multi region design support, qualification labs, and converter reference ecosystems speed adoption across automotive, energy, telecom, and industrial power stages.
Trust matters for safety critical inverters, grid converters, and defense power where qualification data and reliability history decide approvals.
Higher shipment scale improves pricing, allocation priority, and second source credibility for long lifecycle power platforms.
Wafer, packaging, and module assembly capacity determines who can meet ramps for EV charging, renewable inverters, and motor drives.
Post 2023 wide bandgap devices, packaging, and topology enablement decide efficiency, size, and thermal limits in real converter designs.
Strong scoped economics fund capex heavy SiC and GaN ramps and absorb yield learning without disrupting customer programs.
