Alpha & Omega Semi Introduces First Generation AlphaIGBT Technology Platform

Alpha and Omega Semiconductor Ltd. (AOS) introduced a new line of Insulated Gate Bipolar Transistors (IGBTs) to meet the growing need for energy efficient switching devices for motor control and power conversion applications.

AOS introduced its proprietary 600V AlphaIGBT™ technology platform. The AlphaIGBT devices combine a unique cell structure and vertical field stop technique to provide users with best-in-class performance, reducing both conduction and switching losses without compromising short-circuit robustness. The new technology platform is designed for ease-of-use and easy paralleling of devices for high current applications. The low Qgc/Qge ratio allows the devices to withstand higher dV/dt transients and prevents oscillation issues in bridge applications. The AlphaIGBT platform incorporates what the company says is the world’s thinnest IGBT devices fabricated on large diameter 200mm wafers, combined with cutting-edge deep trench technology to raise the bar for IGBT performance. The devices will be available in TO-247, TO-220, TO-220F, TO-262, TO-262F and D2PAK packages.

"By lowering Vce(sat) and Eon/Eoff losses and incorporating a soft recovery diode, AlphaIGBT(TM) technology will be an excellent asset for circuit designers using IGBTs for motor control, photovoltaic inverters and high current power factor correction applications," said Dr. Anup Bhalla, Vice President of High-Voltage Discretes at AOS. "This product delivers very attractive benefits in a whole new range of markets where power requirements are increasingly demanding."

"We are very pleased with the introduction of this new high-voltage technology platform, which marks another important milestone in the continued execution of our strategy. Together with the AlphaMOS™ platform, the AlphaIGBT establishes AOS as a strong player in the high voltage MOSFET and IGBT markets with best-in-class technology," commented Dr. Mike Chang, President and CEO of AOS. "These products will allow us to access the markets for industrial motor control, renewable energy inverters, consumer white goods, and other high voltage applications, achieving our twin goals of product diversification and rapid growth."
