Infineon Technologies 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.
Audio
By continuing to improve audio quality, Class D audio amplifiers are fast becoming the preferred solution for home audio and video systems. Infineon has leveraged its advanced high-voltage technology to offer high-performance MOSFETs and gate driver ICs for Class D audio applications. When combined with the device's ruggedness, customers will receive higher-performance audio systems with higher power density and better reliability.

Industrial
As the industrial market continues to evolve, so does the need for reliable and rugged switching devices. Large battery-driven applications, such as forklifts, uninterruptible power supply (UPS) systems, power tools, electric bikes, and other DC motor-driven systems, are pushing the limits of efficiency and reliability as the need for more power and extended battery life continues to be a staple of newer designs. The need for rugged and efficient MOSFETs is an integral part of these designs. Infineon's latest offering of power MOSFETs meets the demands of these applications as they offer excellent performing devices in a reliable package.

Power Supply
Infineon's Power Supply MOSFETs are designed for AC-DC synchronous rectification in servers, laptop adaptors, and desktop power supplies. In the ongoing quest to increase the power density and speed of data processing circuits, the need for higher-density power supplies continues to grow. This product improves power density by lowering RDS(on) by up to 10% compared to previous industry standards and offers superior synchronous rectification performance through improved RDS(on) in AC-DC SMPS applications.
