Alpha and Omega Semiconductor Announces New 650V and 750V Automotive Qualified αSiC MOSFETs for Industrial and Electric Vehicle Applications
Alpha and Omega Semiconductor Limited (AOSL) has unveiled its new 650V and 750V SiC MOSFET platform tailored for industrial and automotive applications. The 650V variants target industrial uses, while the 750V line is AEC-Q101 qualified for electric vehicle systems. Key features include an ultra-low RDS(ON) of 15mΩ and a more than 40% increase in short circuit withstand time, enhancing ruggedness for EV inverters. These products will be available for orders in Q4/2022, expanding AOSL's portfolio aimed at improved performance and efficiency across various power levels.

The new AOM015V75X2Q 750V αSiC MOSFET expands on the existing second-generation 1200V αSiC MOSFET and diode products with an industry-leading low RDS(ON) down to 15mΩ in a standard TO-247-4L package while maintaining a recommended +15V gate drive voltage to ensure the broadest compatibility with existing gate driver solutions. Due to the minimized internal gate resistance and optimized cell design, AOS designed these devices to exhibit ultra-fast switching speeds that are fully controllable with an external gate resistor. This benefit is also noticeable in standard switching figures-of-merit (FoM) such as RON x QGD and RON x QRR that are improved compared to existing 750V SiC MOSFET solutions.
Highlighting the advantages of these new αSiC MOSFETs is the breakthrough performance increase in short circuit withstand time (SCWT) for planar SiC MOSFETs. For many applications, and especially in EV inverters, a longer SCWT can greatly improve the system’s ruggedness and give developers more flexibility in design. In order to achieve an increase in SCWT, it is typically necessary to also significantly increase the die size of the product, which can impact overall system costs. In AOS tests, these new 750V MOSFETs have maintained a similar or lower RON x A while demonstrating a greater than
“We are very excited to follow up on our successful 1200V αSiC MOSFETs with these automotive-grade 650V and 750V products. Our industrial, renewable energy, and xEV customers will now have a complete portfolio available to select the right solution that supports their wide range of product power levels at an even higher performance and efficiency level,” said
Technical Highlights:
