Power semiconductors. Essential devices for a carbon-neutral future.

By bringing the latest technology advances to high performance power semiconductors, Toshiba Electronic Devices and Storage Corporation is boosting energy conservation in all types of electrical equipment and contributing to a carbon-neutral world.

What they do

Switch on a PC and get down to work. While it adds to your productivity, the PC is also dissipating power—and the same is true for every other electronic device, large and small. Power semiconductors step in to micromanage electricity flows and cut power loss. They deliver energy savings in everything from PCs and smartphones to cars, trains and electricity substations. They may be small, but our high performance power semiconductors make a huge difference.

Our power semiconductors

Customers worldwide rely on our power semiconductor to bring new levels of operating efficiency to their products.

Decarbonized future

Even as the drive for decarbonization intensifies, demand for electricity continues to grow. The need for smaller power converters with low power loss has never been greater, and we are responding by improving the performance of our silicon (Si) devices and introducing wide-bandgap (WBG) semiconductors. We are expanding our Si products lineup and building new manufacturing facilities to boost their production. In our WBG lineup, we have commercialized silicon carbide (SiC) devices and we are developing gallium nitride (GaN) power semiconductors.

SiC power devices
SiC surpasses Si in its high electric breakdown field, saturated electron velocity, and thermal conductivity. It brings higher voltage resistance, higher-speed switching, and lower on-resistance to semiconductors, and is widely seen as a next-generation low-loss device that will advance lower power consumption and system downsizing.

Toshiba GaN power device balances performance and ease of use
Another route to highly efficient, compact power conversion systems is GaN, but it brings its own challenges. Our gate dielectric process technology advances device reliability, and greatly reduces variation in characteristics such as threshold voltage. GaN MOSFETs using this technology will win GaN's further adoption.
