Richardson Electronics and Powerex Offer IGBT Breakthrough...

Ultra-Low Loss NX-S Series IGBT Improves Inverter Performance

LaFox, Illinois: Richardson Electronics, Ltd. (NASDAQ: RELL) and Powerex, Inc., announce off-the-shelf availability of Powerex's breakthrough 6th generation IGBT family. Richardson Electronics carries a substantial inventory of Powerex IGBT devices to support its customers in the Americas. The 6th generation technology includes ultra-low-loss performance (20% lower than the 5th generation IGBT family), while maintaining popular packaging options which are backwards compatible with the 5th generation devices.

"This state-of-the-art IGBT technology paves the way for industry-leading efficiency in new inverter designs," said Kevin Connor, Vice President of the Energy, Power & Interconnect Group at Richardson. "In addition, reduced losses within the device means a lower operating junction temperature and this will lead to reduced space, less weight, and lower overall cost for the thermal management sub-system required to properly cool a given inverter design."

NX-S Series IGBTs in stock at Richardson and available for same-day shipment include:
