Pre-Irradiation
International Rectifier’s R5
TM
technology provides
high performance power MOSFETs for space
applications. 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
paralleling and temperature stability of electrical
parameters.
