International Rectifiers RADHard HEXFET® MOSFET
technology provides high performance power MOSFETs
for space applications. This technology has over a de-
cade of proven performance and reliability in satellite
applications. These devices have been characterized
for both Total Dose and Single Event Effects (SEE). The
combination of low RDS(on) and low gate charge reduces
the power losses in switching applications such as DC to
DC converters and motor control. These devices retain
all of the well established advantages of MOSFETs such
as voltage control, fast switching, ease of paralleling and
temperature stability of electrical parameters.
