Alpha and Omega Semiconductor Releases Robust 600V AlphaMOS-II MOSFET Family

The AOTF11C60 and AOTF20C60 are ideally suited for high-voltage applications where reliability and performance are critical. Such applications include server, telecom and networking power supplies, uninterruptable power supplies, solar inverters, industrial motor control systems, and LED lighting.

AOS’s new AlphaMOS II technology offers a simplified manufacturing process without compromising the core performance of the MOSFET. The AOTF11C60 and AOTF20C60 offer significant improvement in UIS capability over super-junction. Additionally the new family has been optimized for low noise operation and high efficiency by fine tuning the switching parameters. Their low RDS(ON), Ciss and Crss, make the new MOSFETs perfectly suited for designs that require high efficiency, robustness and reliability.

“As efficiency and reliability becomes more and more critical, power designers need high voltage MOSFETs which can withstand reverse recovery current spikes and can also reduce switching and conduction losses. With their unique structure, the new AlphaMOS II products help designers achieve all that in a more robust solution.” said Yalcin Bulut, Vice President of Discrete Product Lines at AOS.
