TECHNOLOGY
Description
IR HiRel RAD-Hard™ HEXFET
®
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 and
temperature stability of electrical parameters.

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.
