MOSFETs reduce lead resistance by half

1 min read

A new series of automotive qualified mosfets has been introduced by International Rectifier. Housed in a WideLead TO-262 package, IR says they offer a 50% reduction in lead resistance compared to traditional TO-262 packages and offer 30% higher current.

The mosfets are designed for generic heavy load/ high power through hole applications requiring low on state resistance, electric power steering and battery switches used in internal combustion engine cars. They combine IR's advanced silicon packaging technologies to offer 'significant performance improvements' while being compatible with existing design standards. "The new WideLead TO-262 package design was inspired by the excellent performance of the ultra low die free package resistance of the DirectFET package and the limitations of the traditional TO-262 package," said Benjamin Jackson, product manager, IR's Automotive Products business unit. "This new range of mosfets housed in IR's novel WideLead package drastically lowers conduction losses and reduces self heating in the leads while delivering high current to provide a robust and reliable solution for automotive applications." The devices are qualified according to AEC-Q101 standards, feature an environmentally friendly, lead free and RoHS compliant bill of materials and are part of IR's automotive quality initiative targeting zero defects.
