AOS semiconductor release 1350V IGBT

Alpha and Omega Semiconductor, a designer, developer and global supplier of power semiconductors and power ICs, today introduced the new E-series IGBT platform with the 1200V AOK20B120E1 and 1350V AOK20B135E1. This new platform has been honed to deliver higher performance by lower switching loss in soft-switching home appliance applications such as induction cooking, rice cookers and inverter-based microwave ovens.

Fast turn-off reduces switching losses and improves system efficiency:

The devices for the E-Series are built upon AOS’s patent pending AlphaIGBT™ technology platform, and feature best-inclass VCE(SAT) and fast turn-off characteristics that reduce the power losses incurred during conduction and switching. The high BVCES rating and rugged BV performance allow for a larger resonant voltage safety margin to prevent avalanche destruction from voltage transients. Moreover, EMI is minimized as a result of very smooth turn-off current waveforms.

“Applications based on induction heating depend on high performance IGBT solutions that help to raise system efficiency and offer long-term reliability.”

said Dr. Brian Suh, Vice President of IGBT product line at AOS. “The 1200V/1350V ESeries has been designed to offer both lower VCE(SAT) and optimized turn-off switching performance.”

AOK20B120E1, AOK20B135E1 Technical Highlights:
