Alpha and Omega Semiconductor Expands its 600V AlphaMOS™ Portfolio
with Rugged Solutions for the Lighting Market
Robust MOSFETs deliver high performance and reliability for LED and CFL lighting
SUNNYVALE, Calif., April 26, 2013 – Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer,
developer and global supplier of a broad range of power semiconductors and power ICs, today announced the release of
AOD4C60, AOD3C60, and AOD2HC60, the newest additions to its 600V AlphaMOS portfolio, which combines features
such as robustness, controlled switching and low on-resistance to produce high-performing devices. These new products are
well suited for commercial and industrial CFL ballasting as well as LED lighting for residential and commercial applications.
These new devices are built using proprietary AlphaMOS technology, designed for efficient switching and dependable
reliability. The device structure of these solutions allows for a smooth dv/dt and di/dt transition during hard switching,
thereby reducing the ringing typically experienced with other superjunction-type devices. Furthermore, these devices offer 3x
the avalanche current capability versus comparable superjunction solutions and enables power circuits to outlast fault
conditions such as power line surges and lighting surges. These solutions are available in 4A, 3A, and 2.5A varieties in the
DPAK green package and are 100% Rg and UIS tested.
“As builders and homeowners move towards replacing conventional lighting fixtures with LED lighting, there is an ever
increasing need for power solutions that are robust and efficient.” said Stephen Chang, Sr. Product Marketing Manager at
AOS. “Our newest 600VAlphaMOS additions offer excellent avalanche ratings in addition to smooth switching performance
to meet these power requirements.”
