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.

Radiation Characteristics
Pre-Irradiation
IRHNA7260, JANSR2N7433U
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.
