SUNNYVALE, Calif., Oct. 29, 2012 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors, today introduced a new high voltage MOSFET silicon technology that offers a more robust alternative to super-junction type products. The AlphaMOS™ II (a patent pending proprietary structure and process) combines planar-like robustness and controlled switching characteristics with the low on-resistance performance of super-junction type devices. The new products based on AlphaMOS™ II are ideally suited for high voltage applications where reliability and performance are critical. Such applications include server, telecom and networking power suppliers, uninterruptible power supplies, solar inverters, industrial motor control systems, and LED lighting.
Over the years, manufacturers of super-junction MOSFETs have commonly migrated to higher-density processes to reduce cost on a specific product performance. In high-power switching applications, this die-shrink approach can create a design dilemma as smaller dies typically compromise die temperature and avalanche energy capability which can jeopardize overall system performance and reliability. AOS's new AlphaMOS II technology offers a simplified manufacturing process without compromising the core performance of the MOSFET. The new devices have been optimized for diode recovery and finely-tuned switching parameters for low noise operation and high efficiency. Additionally, the AlphaMOS II avalanche energy rating (Eas) is about 60% higher than today's leading super-junction offerings of the same current rating, making it perfectly suited for designs that require higher robustness and reliability.
"With its wealth of device technology and application expertise developed over the years, AOS is addressing the major concerns of customers using super-junction parts by providing more robust solutions without sacrificing cost or performance," said Yalcin Bulut, Vice President of Discrete Product Lines at AOS.
AOS will roll-out a complete portfolio of 600V AlphaMOS II products within Q4'2012.
