How WBG devices make swift progress – Accelerating overall assessment of switching characteristics and reliability of power devices
To reach the goal of net-zero emissions by 2050, nations around the world are expressing their aim to ban gas cars in 2035 (2040 for most countries) one after another, which opens up the demands for new energy cars. Driven by the trend of popularization of electric vehicles, currently the applications of automotive semiconductors not only cover integrated circuit (IC), optoelectronic components (LED/VCSEL/PD), and sensors, but also go deeper to the core power system. Power devices and modules play a critical role in inverters, on board charger (OBC) and power factor correction. In addition, wide band-gap (WBG) components, like SiC (Silicon Carbide) and GaN (Gallium Nitride), significantly increase “switching efficiency” and “power density.” That being said, the lifetime and reliability will be challenged under the operation of “high frequency loss” and “high voltage, high current.”

The Crux of WBG Component in Global Green Revolution
The world is now facing an energy crisis, and paying high attention to the solution of optimizing the energy efficiency. As a consequence, the development of WBG (Wide-Band-Gate) becomes one of major subject. Meanwhile, to effectively secure the quality of products, high-level reliability validation and tests are necessary.
