Alpha and Omega Semiconductor (AOS) was established in 2000, the headquarters is located in silicon valley in the United States, is a set design, development and sales for the integration of the global supplier of power semiconductors, AOS provides a wide range of power Semiconductor product line, including full power MOSFET, power management IC and IGBT series products. Has two assembly house of Shanghai and the United States, 8 inch and 12 inch fabs, chongqing is in the valley has all sorts of color of skin of r&d team, makes the AOS has more than 500 patents.

Rich in low voltage MOSFET products (< 40 v), on the PC and BMS application occupies the absolute market share;
Medium voltage MOSFET (40 v, 400 v), product widely covers communications, consumer, industrial, and other fields;
High voltage MOSFET products (> 400 v), can be applied to all kinds of power supply, industrial, lighting and motor drive control.
IGBT products (600 v, 600 v) are widely used in household appliances, consumer driven, industrial class driver, welding machine, air conditioner, induction cooker, new energy, solar power inverter, etc.
