Advanced HEXFET
®
Power MOSFETs from International
Rectifier utilize advanced processing techniques to achieve
extremely low on-resistance per silicon area. This benefit,
combined with the fast switching speed and ruggedized
device design that HEXFET power MOSFETs are well known
for, provides the designer with an extremely efficient and
reliable device for use in a wide variety of applications.
The D
2
Pak 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 D
2
Pak 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.
The through-hole version (IRFZ46NL) is available for low-
profile applications.
