International Rectifier’s RADHardTM HEXFET® technology
provides high performance power MOSFETs for space
applications. This technology has over a decade 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 Rdson 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.

International Rectifier Radiation Hardened MOSFETs are tested to verify their radiation hardness capability.
The hardness assurance program at International Rectifier is comprised of two radiation environments.
Every manufacturing lot is tested for total ionizing dose (per notes 5 and 6) using the TO-3 package. Both
pre- and post-irradiation performance are tested and specified using the same drive circuitry and test
conditions in order to provide a direct comparison.
