Description
Third Generation HEXFETs from International Rectifier provide the designer
with the best combination of fast switching, ruggedized device design, low onresistance and cost-effectiveness.
The 4-pin DIP package is a low-cost machine-insertable case style which can be
stacked in multiple combinations on standard 0.1 inch pin centers. The dual drain
serves as a thermal link to the mounting surface for power dissipation levels up to
1 watt.
