REPETITIVE AVALANCHE AND dv/dt RATED
HEXFET
100 Volt, 0.028
Generation 5 HEXFETs from International Rectifier
utilize advanced processing techniques to achieve
the lowest possible on-resistance per silicon area.
This benefit, combined with the fast switching speed
and ruggedized device design for which HEXFETs
are well known, provides the designer with an extremely efficient device for use in a wide variety of
applications.
The Surface Mount Device 1 (SMD-1) package represents anothther step in the continual evolution of
surface mount technology. Designed to be a close
replacement for the TO-3 package, the SMD-1 will
give designers the extra flexibility they need to increase circuit board density . International Rectifier has
engineered the SMD-1 package to meet the specific
needs of the power market by increasing the size of
the termination pads, thereby enhancing thermal and
electical performance.
