International Rectifier’s RAD-Hard
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 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.

Radiation Characteristics
IRHQ7214
Pre-Irradiation
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.
