Alpha & Omega Semiconductor designs, develops and manufactures leading-edge
discrete and analog power management IC solutions. We offer a comprehensive portfolio
of Power MOSFET, Power IC, and Transient Voltage Suppressor (TVS) products that meet
the complex power requirements of today’s advanced electronic systems and consumer
We specialize in designing innovative analog semiconductors for applications requiring
a smaller product size with maximum efficiency and overall performance. Our propri-
etary process, technology and packaging expertise allows us to design products with a
greater price-to-performance ratio than that of our competitors.
AOS strives to achieve technology breakthroughs ahead of the market. We were the
first semiconductor company to build power devices using submicron 200mm which
enables our products to achieve higher levels of quality and performance.
At AOS, we develop and execute streamlined processes for cost-effective, high-volume
manufacturing. Our dense Trench MOSFET process technology provides leading-edge, low
on-resistance per unit silicon area.
Also, by installing proprietary wafer processing and packaging technologies at partner
foundries, our technical experts can monitor the manufacturing of advanced power products
to guarantee top quality and high performance at low costs.
Quality and Green Commitment
AOS is committed to providing environmentally friendly products that not only meet
RoHS standards, but are also available in Halogen- and Antimony-free options upon
AOS’ global success is attributed to the superior performance and value of solutions
that it offers to customers.
