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 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 (IRF640L) is
available for low-profile applications.
