Pre-Irradiation
International Rectifier’s R5
TM
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.
