Alpha and Omega Semiconductor Introduces New 650V H2-series IGBTs Improved for High-Speed Switching Applications

November 09, 2016

SUNNYVALE, Calif., Nov. 09, 2016 (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, today announced the release of AOK40B65H2AL, the introductory device in the new 650V H2-series IGBT family. The AOK40B65H2AL has been optimized to deliver high-speed switching performance by improving fast turn-off switching in applications such as welding machines, power factor correction and high switching converters.

AOK40B65H2AL has been designed with the latest patent pending AlphaIGBT™ technology platform and features industry-leading fast turn-off and offers low VCE(SAT) at 2.05V, which reduces power loss incurred during conduction and switching. The 650V minimum BVCES rating and solid BV performance allow for a larger safety margin to prevent sudden damage from voltage transients. Furthermore, low turn-on di/dt and high turn-on dv/dt switching performance enable lower EMI design effectively.

"IGBT-driven fast switching converters have been widely used in welding machines, power factor correction, renewable energy applications and so on. Due to higher efficiency, system cost reduction and power quality regulation requirements, the proper selection of the IGBT is crucial to achieving the overall system efficiency robustness, EMI management and long-term reliability," said Dr. Brian Suh, Vice President of IGBT product line at AOS. The 650V H2-series offers designers the ideal combination for higher efficiency, high ruggedness and EMI performance.
