Less wasted energy and longer battery range in electric cars
As the world accelerates its departure from fossil fuels, the quiet machinery of that transition runs on semiconductors — and Mitsubishi Electric has begun placing new ones into the hands of engineers. Starting January 21, the company is shipping samples of four trench SiC-MOSFET bare dies, chips designed to convert electrical power more efficiently inside electric vehicles and renewable energy systems. The move reflects not merely a product launch but a recognition that decarbonization is, at its foundation, an engineering problem — and that the companies who solve it at the component level will shape the infrastructure of the next energy era.
- Global decarbonization mandates are creating structural, not cyclical, demand for power semiconductors — every EV sold and every solar farm built requires multiple conversion chips.
- Mitsubishi's trench design addresses a core tension in power electronics: squeezing more efficiency out of chips while keeping manufacturing costs viable for mass adoption.
- The company is shipping real samples to real customers on January 21, signaling the technology has cleared laboratory validation and is ready for industrial testing.
- A coordinated exhibition strategy spanning Nepcon Japan, North America, Europe, China, and India reveals the competitive urgency — Mitsubishi is racing to become the embedded standard before rivals lock in design wins.
- The stakes are high: a more efficient chip translates directly into longer EV range and more usable grid power from solar installations, making semiconductor performance a visible consumer benefit.
Mitsubishi Electric is beginning to ship samples of four new silicon carbide chips on January 21 — a measured but consequential step in the broader effort to make electric vehicles and renewable energy systems more efficient. These trench SiC-MOSFETs are bare dies, unpackaged semiconductor chips built to handle power conversion inside EV inverters, onboard chargers, and solar installations. The trench architecture allows them to switch electrical current more efficiently than older designs, translating into less wasted energy and greater range for electric vehicles.
The timing is deliberate. Governments worldwide are pressing hard on decarbonization targets, accelerating both EV adoption and renewable energy deployment — and both sectors are only as capable as the power electronics at their core. Mitsubishi is betting these chips will become the standard component embedded in the next generation of equipment, and it is not being subtle about that ambition.
The company will debut the chips at Nepcon Japan in Tokyo, running January 21 through 23, before taking them to trade shows across North America, Europe, China, and India. The global exhibition strategy is a direct play to reach equipment manufacturers and system integrators in every major market where the energy transition is gaining momentum.
What distinguishes this announcement is less the novelty of silicon carbide technology — which has been maturing for years — and more the engineering specificity and production readiness behind it. Shipping samples to potential customers signals that the chips are ready for real-world validation. In a market where every electric vehicle and every solar farm requires multiple power conversion components, the appetite for efficient, cost-manageable semiconductors is structural and growing. Mitsubishi is positioning itself to meet that demand at scale.
Mitsubishi Electric is shipping samples of four new silicon carbide chips starting January 21, marking a quiet but significant move in the race to make electric vehicles and renewable energy systems more efficient. These are bare dies—semiconductor chips without protective casings—engineered to handle the power conversion work inside EV inverters, onboard chargers, and solar power systems. The company is calling them trench SiC-MOSFETs, a technical designation that matters because the trench design allows these chips to switch electrical current more efficiently than older generations, which means less wasted energy and longer battery range in electric cars.
The timing reflects a broader industrial shift. Governments worldwide are pushing hard on decarbonization targets, which has turbocharged demand for electric vehicles and renewable energy infrastructure. Both sectors depend on power electronics—the circuits that convert and regulate electrical current—and those circuits are only as good as the semiconductors at their core. A more efficient chip means an EV can travel farther on a charge, or a solar installation can feed more usable power back to the grid. Mitsubishi Electric is betting that these new bare dies will become the standard component that equipment makers embed in their next generation of products.
The company is not keeping this development quiet. Beginning January 21, Mitsubishi will display the new chips at Nepcon Japan, a major manufacturing and research trade show in Tokyo running through January 23. But the real ambition is global. The company plans to exhibit these same chips at trade shows across North America, Europe, China, India, and elsewhere—a deliberate strategy to reach equipment manufacturers and system integrators in every major market where EV adoption and renewable energy deployment are accelerating.
What makes this announcement noteworthy is not the novelty of silicon carbide semiconductors themselves—that technology has been in development for years—but rather the specific engineering approach and the scale at which Mitsubishi is preparing to produce them. The trench design is meant to improve performance while keeping costs manageable. The fact that the company is already shipping samples to potential customers suggests the technology is mature enough for real-world testing, not just laboratory validation.
The power semiconductor market is expanding because the underlying demand is structural and durable. Every electric vehicle sold needs multiple power conversion chips. Every solar farm needs them. Every battery storage system needs them. As global vehicle electrification accelerates and renewable energy capacity grows, the appetite for these components will only deepen. Mitsubishi Electric is positioning itself as a supplier that can meet that demand with chips that help equipment makers hit their own efficiency targets—a value proposition that resonates in a world where energy efficiency has become a competitive advantage.

La Conversación del Hearth Otra perspectiva de la historia
Why does a company announce the shipment of chip samples? Isn't that something that happens quietly in supply chains?
Because this is a signal to the entire industry. When Mitsubishi says samples are shipping, they're telling equipment makers, investors, and competitors that the technology works and is ready for integration. It's a credibility marker.
And the trench design—is that a major breakthrough, or incremental improvement?
It's incremental in the sense that silicon carbide itself isn't new. But the trench architecture is how you squeeze more efficiency out of the same material. In power electronics, even small efficiency gains compound across millions of devices.
Why does Mitsubishi need to exhibit at shows in five different regions?
Because power electronics equipment makers are distributed globally. A solar inverter manufacturer in Germany needs to know about these chips just as much as one in Japan. You can't win the market by showing up in one place.
What happens if these chips don't perform as promised in real equipment?
Then the samples don't convert to production orders, and Mitsubishi loses market share to competitors. That's why they're shipping samples now—to let customers test them under actual conditions before committing to large volumes.
Is this about beating competitors or meeting customer demand?
Both. The demand is real and growing. But there are other companies making SiC chips. Mitsubishi is trying to be the supplier that customers choose because the technology is proven and the company can deliver at scale.
