Teradyne and Lemsys announced Teradyne's acquisition of the privately-held, high-power semiconductor test equipment maker Lemsys SA based in Geneva, Switzerland. The Lemsys product portfolio includes test equipment for IGBT, MOSFET, power modules, intelligent power modules (IPM), diodes, and thyristors. The Swiss company serves the emerging and growing power discrete device and module market aligned to electric vehicles, wind and solar power generation, as well as high-power industrial applications.

The acquisition is expected to expand Teradyne's role in the emerging and fast-growing power discrete test market. Also, the Massachusetts firm, Teradyne, says that the acquisition gives customers a portfolio of power discrete test solutions from R&D to high volume production. Lemsys will reportedly be able to take advantage of Teradyne's global distribution and financial strength. The 21-person company will remain in Geneva with current management and staffing.

"Lemsys is the market leader in the emerging high power discrete segment of the semiconductor test market and we are very excited to have Lemsys join Teradyne," said Greg Smith, President of Teradyne's Semiconductor Test Division. "With its talented team and industry-leading product line, Lemsys will expand the range of test solutions we can offer to power semiconductor customers."

"We are excited to join forces with Teradyne to expand our product development and market growth through Teradyne's world-class engineering and customer support capabilities," said Giuseppe Santandrea, CEO of Lemsys. "With Teradyne, we will be able to grow our production footprint not only in China and Europe, but around the world."
