SUNNYVALE, Calif., Dec. 18, 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 released a family of low on-resistance 8V, 20V, and 30V MOSFETs in the ultra-thin molded chip scale package (MCSP). The MCSP devices feature a maximum height of only 0.3mm to provide a perfect solution for ultra-slim designs. Compared to existing CSP solutions the new family reduces package height by 50% and improves the overall mechanical robustness of the package. The noteworthy performance enhancements offered by the MCSP technology, make these new devices ideal for the latest ultra-portable applications such as smart phones, tablet PCs, Ultrabooks, and other mobile hand-held devices.

The proprietary MCSP packaging technology encapsulates AOS's low on-resistance MOSFET silicon in a protective Green (halogen-free) molding compound. The resulting product provides a thinner and more robust structure to solve die chipping and placement issues associated with standard CSP products. The new family of MCSP devices offers major performance benefits and at the same time can easily replace industry standard CSP devices by offering the same footprint, pin-out, and pitch.

"The new family of molded chip scale devices, offer our customers an unparalleled solution for space and height constrained ultra-portable designs. The combination of AOS's advanced packaging and MOSFET silicon technologies allow designers to keep pushing the space and height limits of advanced ultra-portable applications," said Peter Wilson, Director of Low Voltage MOSFETs at AOS.

The new portfolio of MCSP products includes n- and p-channel devices with VDS ratings from 8V to 30V in package options of 0.97mm x 0.97mm and 1.57mm x 1.57mm. AOC2414, AOC2421, and AOC2422 have guaranteed ultra-low on-resistance rated at 1.2VGS which helps designers to simplify drive circuitry, lower power consumption and extend battery life in ultra-portable applications.
