IR launches new MOSFET offering increased power density while reducing system size and cost

International Rectifier has launched 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 minimise conduction losses. The dual-side cooling Medium Can DirectFET 2 power package provides thermal performance and low parasitic inductance.

The device combines the performance of the COOLiRFET silicon with the DirectFET 2 package, delivering a 40% Rds(on) improvement in the same footprint, or equivalent performance to a Large Can device in a 50% smaller package.

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.
