International Rectifier’s RAD HARD technology
HEXFETs demonstrate virtual immunity to SEE fail-
ure.Additionally, under identical pre- and post-radia-
tion test conditions, International Rectifier’s RAD HARD
HEXFETs retain identical electrical specifications up
to 1 x 105 Rads (Si) total dose. No compensation in
gate drive circuitry is required.These devices are also
capable of surviving transient ionization pulses as high
as 1 x 1012 Rads (Si)/Sec, and return to normal opera-
tion within a few microseconds. Since the RAD HARD
process utilizes International Rectifier’s patented
HEXFET technology, the user can expect the highest
quality and reliability in the industry.
RAD HARD HEXFET transistors also feature all of the
well-established advantages of MOSFETs, such as
voltage control, very fast switching, ease of parallel-
ing and temperature stability of the electrical param-
eters.
They are well-suited for applications such as switch-
ing power supplies, motor controls, inverters, chop-
pers, audio amplifiers and high-energy pulse circuits
in space and weapons environments.
