COOLiRFET power MOSFETS run cooler than conventional MOSFETs

September 19, 2013 // By Christoph Hammerschmidt
Mouser Electronics, Inc. now stocks International Rectifier’s (IR) family of AEC-Q101 automotive qualified 40V N-channel MOSFETs, featuring IR’s proven Gen12.7 trench technology with ultra-low Rds(on).

International Rectifier's Automotive COOLiRFET Power MOSFETs from Mouser Electronics target rugged automotive applications. These HEXFET Power MOSFETs utilize leading-edge manufacturing techniques to achieve very low on-resistance, resulting in highly efficient switching of high current signals with very little power loss. Additional features include a high 175°C junction temperature, fast switching speeds for better power efficiency, and a high repetitive avalanche rating for harsh signal environments. These new devices offer low conduction losses and robust avalanche performance to deliver higher efficiency, power density and reliability. Applications using these new IR COOLiRFET devices from Mouser Electronics can run significantly cooler than comparable MOSFETs. These features combine to make this an extremely efficient and reliable MOSFET for use in automotive systems as well as a wide variety of other applications.
