Oct 10, 2013 | Technology Media

EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced the introduction of 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 DirectFET®2 power package delivers excellent thermal performance and low parasitic inductance.

"Combining the performance of the COOLiRFET™ silicon with the DirectFET®2 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 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.

Part Number Package Vds Rds(on)
AUIRF8736M2 DF2 M Can 40V 1.3mOhm 1.9mOhm 137A 136nC

Datasheets, application notes and qualification standards are available on the International Rectifier website.
