This benefit, combined with the fast switching speed and ruggedized device design that HEXFET Power MOFETs are well known for, provides the designer with an extremely efficient device for use in a wide variety of applications. The O-8 has been modified through a customized leadframe for enhanced thermal characteristics and multiple-die capability making it ideal in a variety of power applications. With these improvements, multiple devices can be used in an application with dramatically reduced board space. The package is designed for vapor phase, infra red, or wave soldering techniques. Power dissipation of greater than 0.8W is possible in a typical PCB mount application. V = 30V R (on) = 0.022Ω O-8 bsolute Maximum Ratings Parameter Max. Units T = 25 C ec.
