Description
AdvancedHEXFET® PowerMOSFETsfromInternational
Rectifierutilizeadvancedprocessingtechniquestoachieve
extremelylowon-resistancepersiliconarea. Thisbenefit,
combined with the fast switching speed and ruggedized
device design that HEXFET power MOSFETs are well
knownfor,providesthedesignerwithanextremelyefficient
andreliabledeviceforuseinawidevarietyofapplications.
The TO-220 package is universally preferred for all
commercial-industrial applications at power dissipation
levels to approximately 50 watts. The low thermal
resistance and low package cost of the TO-220 contribute
to its wide acceptance throughout the industry.
