International Rectifier has introduced the AUIRF8736M2 DirectFET2 power MOSFET for heavy load automotive applications, including electric power steering, braking systems, and pumps that need high power density in a compact footprint. The company said the product, which leverages on IR's COOLiRFET silicon technology, allows for increased power density while reducing overall system size and cost.

The 40V AUIRF8736M2 offers a 40 per cent improvement in on-state resistance (Rds(on)) compared to previous generation devices to help minimise conduction losses, the company said. The dual-side cooling Medium Can DirectFET2 power package delivers high thermal performance and low parasitic inductance.

"Combining the performance of the COOLiRFET silicon with the DirectFET2 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 David Poon, IR's vice president, AsiaPac Sales.

The device is qualified according to AEC-Q101 standards, features an environment-friendly package and RoHS compliant bill of materials, and is part of IR's automotive quality initiative targeting zero defects.

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