Automotive power MOSFETs allow smaller, lower-cost system designs

October 11, 2013 // By Paul Buckley
International Rectifier has introduced the AUIRF8736M2 DirectFET2 power MOSFET for heavy load automotive applications including electric power steering, braking systems and pumps that require superior power density in a compact footprint.

Applying IR’s benchmark COOLiRFET silicon technology, the 40-V AUIRF8736M2 offers a 40% improvement in on-state resistance (R ds(on)) compared to previous generation devices to help minimise conduction losses. The dual-side cooling Medium Can DirectFET2 power package delivers thermal performance and low parasitic inductance.

The device is qualified according to AEC-Q101 standards, features a 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 $0.82 each for the AUIRF8736M2 (10,000)
