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.
