Alpha and Omega Semiconductor Announces Silicon Carbide License Deal and Supply Agreement

Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of power semiconductors announced today that it has entered into a license agreement with a leading power semiconductor automotive supplier related to AOS’s Silicon Carbide (SiC) MOSFET and diode technology. In the agreement AOS will license and provide engineering support for its proprietary aSiC technology as well as an accompanying supply agreement.

Silicon Carbide is a next-generation power semiconductor technology can enable automotive manufactures to produce electric vehicle (EV) powertrain and charging systems with smaller size and higher efficiency resulting in faster charging and extended operating range. The SiC market is one of the fastest growing segments in the power semiconductor market with an estimated $6 billion total addressable market size by 2027. AOS’s class leading automotive aSiC MOSFETs are available from 750V to 1200V, covering the majority of 400V and rapidly expanding 800V EV battery systems.

“We are very excited to enter this new license and supply agreement that further validates the technical leadership of our aSiC technology,” said David Sheridan, vice president of SiC products at AOS. “This will provide a great acceleration of our products into the market and have the potential for our customers to secure a geographically diverse supply chain to reduce regional risk.”
