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 product are
a 175°C junction operating temperature, fast switching speed and im-
proved 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.
The D-Pak is designed for surface mounting using vapor phase, infrared,
or wave soldering techniques. The straight lead version (IRFU series) is
for through-hole mounting applications. Power dissipation levels up to
1.5 watts are possible in typical surface mount applications.
