Product Summary

The IRF740 is a Single N-Channel HEXFET Power MOSFET. The IRF740 provides the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness. The TO-220 package is universally preferred for all commercial-industrial applications at power dissipation levels to approximately 50 W. The low thermal resistance and low package cost of the TO-220 contribute to its wide acceptance throughout the industry.
