MOSFET
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 R
DS(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.

Radiation Characteristics
Pre-Irradiation
IRHQ9110
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.
