Generation V Technoogy Utra Low On-Resistance N-Channe Mosfet Surface Mount vaiabe in Tape & Ree ynamic dv/dt Rating Fast Switching 00% R G Tested Lead-Free escription Fifth Generation HEXFETs from Internationa Rectifier utiize advanced processing techniques to achieve extremey ow on-resistance per siicon area. This benefit, combined with the fast switching speed and ruggedized device design that HEXFET Power MOSFETs are we known for, provides the designer with an extremey efficient and reiabe device for use in a wide variety of appications. The SO-8 has been modified through a customized eadframe for enhanced therma characteristics and mutipe-die capabiity making it idea in a variety of power appications. With these improvements, mutipe devices can be used in an appication with dramaticay reduced board space. The package is designed for vapor phase, infra red, or wave sodering techniques. Power dissipation of greater than 0.8W is possibe in a typica PCB mount appication.
