IRs Automotive DirectFET2 Power MOSFET increases power density while reducing system size and cost



International Rectifier, a leader in power management technology, 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.
