Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only; and functional operation of the device at these or any other condition beyond those indicated in the specifications is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. The thermal resistance
and power dissipation ratings are measured under board mounted and still air conditions. Ambient temperature (TA) is 25°C, unless
otherwise specified.

Description
Specifically designed for Automotive applications, this cellular design of
HEXFET® Power MOSFETs utilizes the latest processing techniques to
achieve 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 Automotive and a wide variety of other
applications.
