Alpha and Omega Semiconductor Announces New 1200V, 40A H1 IGBT Optimized for High Switching Frequency Applications

SUNNYVALE, Calif., Sept. 12, 2017 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors and power ICs, is expanding its recently launched fast turn-off switched 650V H-series IGBT family with a 1200V rating. The new AOK40B120H1 has been developed to address needs of industrial welding and high-frequency converters with 3-phase ac or high voltage dc input. The device offers excellent performance in high switching frequency applications, which can be a perfect fit for high voltage industrial welding machines.

The AOK40B120H1 has been designed with AOS’ patent pending AlphaIGBT™ technology platform and features industry-leading fast turn-offas well as low VCE(SAT) of 1.8V, which reduces power losses incurred during conduction and switching. Also, the 1200V minimum BVCES rating and high latch-up ruggedness enable a larger safety application design.

“The AOK40B120H1 comprehensively addresses the needs of 1200V discrete IGBT-based welding system designers. High performance such as low VCE(SAT) and low loss of turn-off switching behaviors ensure reliable and highly efficient operation, allowing designers to take advantage of cost effectiveness,” said Dr. Brian Suh, Vice President of IGBT product line at AOS. “AOS IGBTs are uniquely positioned to address customer pain points with innovative technology and solutions.”
