Power MOSFETs

Infineon pioneered HEXFET power MOSFET technology, developing and introducing the first hexagonal topology MOSFETs in 1979. These developments were granted a broad patent just four years later, and since that time, most MOSFET manufacturers have licensed the designs and processes to enter this marketplace. IR products exhibit the lowest MOSFET on-resistance available on the market for similar components in their class, enabling power conversion subsystem designs that exhibit unequaled efficiency. IR combines state-of-the-art silicon technology with innovative packaging technology. IR POWIRTAB™, Super-220™, and Super-247™ packages allow up to 20A more current per device in the same footprint than standard packages, increasing power density. Compatible with standard surface-mount soldering techniques, IR's FlipFET® packaging technology offers a 100% silicon-to-footprint ratio with the same performance as a conventional package three times as big, making it the ideal solution for portable devices such as phones or notebook PCs. IR's DirectFET® packaging revolutionizes thermal management in the footprint of a standard SO-8 by drawing heat away from the board through the top of the package. As a result, DirectFET MOSFETs can double the current density while cutting thermal management costs in half in high-current circuits that power next-generation microprocessors.
