Alpha and Omega Semiconductor Limited (AOS), a global designer and supplier of a wide range of power semiconductors and power integrated circuits, is expanding its family of fast-switching IGBT devices in its H-series 1200V class. These new devices are designed to meet the growing demands of high-frequency industrial applications, particularly in welding systems and high-voltage power converters.
One of the latest products, the AOK40B120H1, has been developed to support industrial welding equipment and high-frequency converters operating with three-phase AC input or high-voltage power systems. It delivers strong performance in high switching frequency environments, making it well suited for heavy-duty industrial welding machines and other demanding power conversion systems.
The AOK40B120H1 is built on Alpha and Omega Semiconductor’s proprietary AlphaIGBT™ technology platform. It features fast switching capability and a low VCE(sat) of approximately 1.8V, which helps reduce both conduction and switching power losses. This improves overall system efficiency and thermal performance in industrial applications.
With a 1200V minimum BVCES rating and strong latch-up robustness, the device provides improved safety margins and more reliable operation under challenging electrical conditions. These characteristics make it suitable for engineers designing high-reliability industrial systems that require both performance and durability.
According to Dr. Brian Suh, Vice President of the IGBT Product Line at AOS, the AOK40B120H1 is designed specifically to meet the needs of system designers working with 1200V IGBT-based welding applications. Its low conduction losses and optimized switching behavior enable efficient and reliable operation while also supporting cost-effective system design. AOS IGBTs are positioned to address key challenges faced by customers through innovative semiconductor technology and application-focused solutions.
Overall, the new generation of Alpha and Omega Semiconductor IGBTs demonstrates continued advancements in power semiconductor design, supporting higher efficiency, improved reliability, and better performance in industrial welding and high-power conversion applications.
