SUNNYVALE, Calif.--(BUSINESS WIRE)--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 the new 1200V silicon carbide (SiC) αSiC MOSFET technology platform. Specifically targeting the industrial and automotive market, this next-generation technology will enable customers to achieve higher levels of efficiency and power density compared to existing silicon solutions.
Optimized for minimizing both AC and DC power losses through a low gate resistance (RG) design combined with the low increase in on-resistance (RDS,ON) over temperature, the αSiC technology can achieve the highest efficiencies across a wide range of application switching frequencies and temperatures. This higher efficiency can result in significantly reduced system costs and total bill-of-materials for the many industrial uses, including solar inverters, UPS systems, and EV inverter and charging systems.
The first product release for this new platform is the AOK065V120X2, a 1200V 65mΩ SiC MOSFET available in a TO-247-3L package. For ease of use, the AOK065V120X2 is designed to be driven with a -5V/+15V gate drive, allowing the broadest compatibility with existing high voltage IGBT and SiC gate drivers. Operation with a unipolar drive is also possible with optimized system design. Additional benefits of the αSiC platform is a robust UIS capability, enhanced short circuit performance, and a high maximum operating temperature of 175oC.
“After years of development work, we are excited to add this new next-generation SiC MOSFET technology to Alpha and Omega’s existing class-leading Si MOSFET and IGBT portfolio. Adding to our previously released 650V GaN platform, the αSiC devices further expand our positioning for the projected multi-billion dollar wide bandgap power semiconductor market. We are committed to providing the optimal technology solution for each customer’s needs,” said David Sheridan, Sr. Director of Wide Bandgap Products at AOS.
The AO7400 power MOSFET from Alpha & Omega Semiconductor provides the solution. Its maximum power dissipation is 350 mW. This MOSFET transistor has a minimum operating temperature of -55 °C and a maximum of 150 °C. This N channel MOSFET transistor operates in enhancement mode. If you need to either amplify or switch between signals in your design, then Alpha & Omega Semiconductor's AO3424 power MOSFET is for you. Its maximum power dissipation is 1400 mW.

SUNNYVALE, Calif.--(BUSINESS WIRE)--Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of power semiconductors, power ICs, and digital power products today, today announced a new family of active AC-DC bridge rectifiers. Aptly trademarked AlphaZBL™ for “zero bridge loss,” this new family of products virtually eliminates the bridge rectifier losses in AC-DC power supplies and adaptors. Typical end applications include high power 100W and above adaptors used for high-end laptops and televisions as well as power supplies for Desktops, Game consoles, Servers, and Telecom.
The first two members of the family include a controller, AOZ7200, in a SOT-23 package and an integrated product AOZ7270, which integrates a 600V, 190mOhm MOSFET in a DFN 5x7 package. The AOZ7200 offers maximum flexibility to trade off performance and cost by pairing it with AOS’s benchmark super junction family of MOSFETs. The AOZ7270 takes advantage of AOS’s capabilities in novel IC design, benchmark MOSFET technology, and innovative packaging to reduce component count and design time. Both products are self-powered from the AC line and do not require external circuitry. The proprietary self-biasing scheme sips minimal power from the AC line making it very efficient in light load or standby mode of operation. In a typical 100W application, the AOZ7270DI delivers efficiency improvements of 0.89% at 115VAC and 0.44% at 230VAC over a diode bridge. Both products exceed lightning surge requirements that are a critical requirement in AC-DC applications.
“Today’s data centers strive for improved efficiency and thermals as cooling of the data center takes as much if not more power than the servers themselves. AOS’s AlphaZBL products make the design of Titanium grade efficiency power supplies far easier to achieve,” said Colin Huang, Power IC Marketing Manager at Alpha and Omega Semiconductor. “High power adaptors face thermal challenges in the face of ever-increasing power density. Active bridge rectification enabled by AOZ7200 and AOZ7270 offer the simplest path to reducing power losses,” he adds.
