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 (T
A
) is 25°C, unless otherwise specified.
Description
Specifically designed for Automotive applications,
this HEXFET
®
Power MOSFET utilizes the latest
processing techniques to achieve extremely low on-
resistance per silicon area. Additional features of
this design are a 175°C junction operating tempera-
ture, fast switching speed and improved repetitive
avalanche rating . These features combine to make
this design an extremely efficient and reliable device
for use in Automotive applications and a wide variety
of other applications.
