thermal management. Here is where the difference between the datasheet and the application really stands out. “The semiconductor suppliers cannot cover every application,” said Mashaly, who is also head of the new laboratory. “There will be points in the final application that are not covered in the datasheet. Power semiconductors are used in different applications with different loads. They are also used everywhere in the world, so environmental conditions and grid performance have to be considered.” To help engineers tackle these problems, Rohm decided to provide local technical support at the application level in Europe, and so the Power Lab was born. The engineers employed there will look at how its customers are using the devices and provide support for them through all phases of the project with the focus being at the system rather than component level. “We can perform special tests for a customer at the application level,” said Mashaly. “With the Power Lab, we can show how the parts work together.” The 300m² lab’s purpose is the analysis of power components and LAB WORK systems to provide support at the application level. To that end, it is Steve Rogerson equipped with several test ith increases in traditional datasheets often do not Semiconductor opening its Power more complex, they have limited benches with a separate high- visits Rohm complexity and cover every possible use case.
