The current density of this new 650V IGBT was improved by 30% compared to the prior generation by adopting the latest technology. This IGBT is also designed to provide a minimum short-circuit withstand time of 5µs and it is optimized for parallel switching because of its positive temperature coefficient. The parallel switching of this IGBT will increase the load current and thus the maximum output power.

“Magnachip’s first IGBT was introduced in 2013, and since then, we have been committed to developing high-efficiency products for a variety of markets, while strengthening our presence around the world,” said YJ Kim, CEO of Magnachip. “With this new product, we are expanding our efforts to deliver high-performance products for the eco-friendly renewable energy market.”

In addition, the 650V IGBT features anti-parallel diodes for fast switching and low switching loss, while guaranteeing a maximum operating junction temperature of 175°C. Based on standards issued by the Joint Electron Device Engineering Council (JEDEC), this new IGBT can be widely used for applications requiring strict power level and high efficiency, such as solar boost inverters and converters, uninterruptible power supplies and universal power inverters.

Omdia, a global market research firm, estimates that the global market for IGBTs in the renewable energy sector will grow 15% annually from 2022 to 2025.

Magnachip is a designer and manufacturer of analog and mixed-signal semiconductor platform solutions for communications, IoT, consumer, computing, industrial and automotive applications. With more than 40 years of operating history, owns a portfolio of approximately 1,150 registered patents and pending applications, and has extensive engineering, design and manufacturing process expertise.

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We discuss everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
