IR Introduces Family of Large Can DirectFET® MOSFETs Featuring Ultra-low Rds(on) for Industrial Applications

Jun 12, 2014 | Technology Media

EL SEGUNDO, Calif. — International Rectifier, IR ® (NYSE: IRF), a world leader in power management technology, today introduced the introduction of a family of Large Can DirectFET ® MOSFETs for industrial applications requiring ultra-low on-state resistance (Rds(on)) including high power DC motors, DC/AC inverters, and high current switching applications such as active ORing hot swap, and eFuse.

The new 7mm x 9mm x 0.7mm Large Can devices provide superior Rds(on) performance leading to lower conduction losses and improved system efficiency. Similar to Small and Medium Can DirectFET ® devices, the Large Can provides dual-side cooling that can maximize thermal transfer and help increase power density. DirectFET ® also has the optimum die-to-footprint ratio, leading to a reduction in board space. Combined with its ultra-low profile (0.7mm), it is the ideal solution for space constrained, high power industrial power designs.

As with the entire DirectFET ® family, the new industrial Large Can has wire bond-free construction for improving reliability performance. Moreover, the DirectFET ® package meets all RoHS requirements such as a completely lead-free bill of materials, and is, therefore, well suited for long lifecycle designs. Alternative high performance packages feature lead die attach under RoHS exemption 7(a) which is due to expire in 2016.

"With the addition of the Large Can, DirectFET ® continues to lead the industry as one of the most reliable and highest performing MOSFET packages on the market. By offering a significantly smaller footprint than traditional large plastic surface mount power packages like D2PAK, and, in addition to the ability to top-side cool, the new Large Can DirectFET ® family is ideally suited for space constrained long life industrial power designs," said Brian LaValle, Marketing Manager for IR's Power Management Devices Business Unit.

The new 40V - 150V Large Can devices are qualified to industrial grade and moisture sensitivity level 1 (MSL1).
