EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced a family of automotive-qualified COOLiRFET™ MOSFETs delivering benchmark on-state resistance (Rds(on)) for heavy load applications including electric power steering (EPS), braking systems and other heavy loads on internal combustion engine (ICE) and micro hybrid vehicle platforms.

The family of 22 AEC-Q101 qualified 40V N-channel MOSFETs feature IR’s proven Gen12.7 trench technology that delivers ultra-low Rds(on) in D2Pak-7P, D2Pak, DPak, TO-262, IPAK and TO-220 packages. The benchmark D2Pak-7P AUIRFS8409-7P delivers Rds(on) max as low as 0.75mOhm at 10Vgs with a current rating up to 240A. The new devices offer low conduction losses and robust avalanche performance to deliver higher efficiency, power density and reliability. With this performance, many applications using these new COOLiRFET™ devices run significantly cooler than with state-of-the-art MOSFETs.

“IR's new family of COOLiRFET™ 40V automotive-qualified MOSFETs achieves benchmark Rds(on) in all package variations to deliver a highly efficient solution for high current automotive applications requiring high performance while reducing overall system cost,” said Jifeng Qin, Product Manager, Automotive MOSFETs, IR’s Automotive Products Business Unit.

IR’s automotive MOSFETs are subject to dynamic and static part average testing combined with 100 percent automated wafer level visual inspection as part of IR’s automotive quality initiative targeting zero defects. The new devices are AEC-Q101 qualified, which requires that there is no more than a 20 percent change in Rds(on) after 1,000 temperature cycles of testing, and feature an environmentally friendly, lead-free and RoHS compliant bill of materials.
