PCIM Europe: 40V automotive MOSFETs With Benchmark on-State Resistance

International Rectifier has strengthened its family of automotive-qualified COOLiRFET MOSFETs with the addition of 22 new devices in differing packages. The 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. IR says the devices meet efficiency and performance requirements while reducing overall system costs.
The 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.
These 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.
