Automotive DirectFET2 Increases Power Density and Reduces System Size and Cost

October 09, 2013 by Jeff Shepard

International Rectifier Corp. (IR) has introduced the AUIRF8736M2 DirectFET®2 power MOSFET for heavy load automotive applications including electric power steering, braking systems and pumps that require superior power density in a compact footprint. Leveraging IR’s benchmark COOLiRFET™ silicon technology, the 40V AUIRF8736M2 offers a 40% improvement in on-state resistance (Rds(on)) compared to previous generation devices to help minimize conduction losses. The dual-side cooling Medium Can DirectFET2 power package delivers excellent thermal performance and low parasitic inductance.

“Combining the performance of the COOLiRFET™ silicon with the DirectFET2 package, the AUIRF8736M2 delivers a 40% Rds(on) improvement in the same footprint, or equivalent performance to a Large Can device in a 50% smaller package reducing overall system size and cost for automotive applications,” said Jifeng Qin, Product Manager, Automotive MOSFETs, IR’s Automotive Products Business Unit.

The AUIRF8736M2 features a typical on-resistance of 1.3 mOhms, a maximum on-resistance of 1.9 mOhms, a drain current rating of 137A and a typical Qg of 139nC. The device is qualified according to AEC-Q101 standards, features an environmentally-friendly 100% lead-free package and RoHS compliant bill of materials, and is part of IR’s automotive quality initiative targeting zero defects. Pricing begins at US $0.82 each for the AUIRF8736M2 in 10,000-unit quantities. Production orders are available immediately.
