New Automotive-Grade MOSFETs Available from RS Components Deliver Ultra-Low On-State Resistance



COOLiRFET(TM) family from International Rectifier offers high efficiency for high current, high performance automotive applications

RS Components( http://www.rs-components.com ) (RS), the trading brand of Electrocomponents plc( http://www.electrocomponents.com ) (LSE:ECM), the world's leading high service distributor of electronics and maintenance products, has announced availability of a new family of automotive-qualified COOLiRFET(TM) MOSFETs from International Rectifier( http://www.rs-components.com/coolirfet-mosfets ) (IR), the world leader in power management technology.

The new devices deliver 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.

Qualified to AEC-Q101, the 22 new 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(TM) devices run significantly cooler than with state-of-the-art MOSFETs.

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.

All variants in IR's COOLiRFET(TM) family are available to purchase direct from RS stock for same-day despatch at www.rs-components.com.
