Description
Third Generation HEXFETs from International Rectifier
provide the designer with the best combination of fast
switching, ruggedized device design, low on-resistance
and cost-effectiveness.
The SOT-227 package is universally preferred for all
commercial-industrial applications at power dissipation
levels to approximately 500 watts. The low thermal
resistance of the SOT-227 contribute to its wide acceptance
throughout the industry.
