International Rectifier's RAD-Hard HEXFET

technol-

ogy 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 character-
ized 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 elec-
trical 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.
