Power semiconductors, including IGBT technology, are gaining widespread adoption across high-voltage and high-power applications due to their efficiency and reliability. However, modern industrial systems demand components that not only deliver high performance but also maintain low power losses, high switching speed, and long-term reliability. Expanding its portfolio, ROHM Semiconductor has introduced its 3rd generation IGBT, designed to meet the growing need for high-efficiency power switching solutions.
Building on its existing lineup of high-current IGBTs and low saturation voltage devices, ROHM’s latest generation focuses on achieving superior performance in high-frequency switching applications. The new devices utilize a thinner wafer structure, along with advanced field-stop technology and a proprietary trench gate structure, enabling improved electrical characteristics and enhanced efficiency.
The 650V 3rd generation IGBT from ROHM is based on an advanced field-stop structure that reduces the carrier concentration gradient in the drift region. This improvement enhances carrier distribution, resulting in lower saturation voltage (Vce(sat)) and faster switching speed. These features provide an optimal balance between conduction losses and turn-off losses, which is a key advantage over conventional IGBT solutions.
With improved switching performance and reduced energy loss, these high-efficiency IGBT modules are ideal for applications such as industrial inverters, motor drives, power supplies, renewable energy systems, and electric vehicles. The enhanced design supports better thermal performance and contributes to increased overall system efficiency.
ROHM Semiconductor continues to innovate in the field of power electronics and IGBT technology, delivering solutions that meet the evolving demands of modern industries. The introduction of its 3rd generation IGBTs highlights the company’s commitment to providing high-performance, energy-efficient, and reliable power semiconductor devices for next-generation applications.
