TECHNOLOGY
SMD-1
International Rectifier’s R5 technology provides
high performance power MOSFETs for space appli-
cations. These devices have been characterized for
Single Event Effects (SEE) with useful performance
up to an LET of 80 (MeV/(mg/cm
2
)). 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 paral-
leling and temperature stability of electrical param-
eters.

Radiation Characteristics
IRHN57250SE
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.
