Automotive power MOSFET increases power density while reducing system size and cost

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 (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.

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.

Availability and Pricing

Pricing begins at $0.82 each for the AUIRF8736M2 in 10,000-unit quantities. Production orders are available immediately.
