Alpha and Omega Semiconductor- new 650V H2 series

Alpha and Omega Semiconductor Limited, a designer, developer and global supplier of a broad range of power
semiconductors and power ICs, 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.
