Description

Fifth Generation HEXFETs 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 TO-220 Fullpak eliminates the need for additional
insulating hardware in commercial-industrial applications.
The moulding compound used provides a high isolation
capability and a low thermal resistance between the tab
and external heatsink. This isolation is equivalent to using
a 100 micron mica barrier with standard TO-220 product.
The Fullpak is mounted to a heatsink using a single clip or
by a single screw fixing.
