Description
IR HiRel RADHard™ HEXFET
®
MOSFET technology provides
high performance power MOSFETs for space applications.
This technology has long history 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 and temperature stability of electrical

Radiation Characteristics
Pre-Irradiation
IR HiRel Radiation Hardened MOSFETs are tested to verify their radiation hardness capability. The hardness assurance
program at IR HiRel 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.
