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 D
Pak is a surface mount power package capable of the accommodatingdie sizes
up to HEX-4. It provides the highest power capability and the lowest possible onresistance in any existing surface mount package. The D
current applications because of its low internal connection resistance and can
dissipate up to 2.0W in a typical surface mount application. The through-hole version
(IRFBF20L) is available for low-profile applications.
