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 SMD-220 is a surface mount power package capable of accommodating
die sizes up to HEX-4. it provides the highest power capability and the lowest
possible on-resistance in any existing surface mount package. The SMD-220
is suitable for high current applications because of its low internal connection
resistance and can dissipate up to 2.0W in a typical surface mount application.
