SINGLE EVENT EFFECT (SEE) RAD HARD
500 Volt, 0.32Ω, (SEE) RAD HARD HEXFET
International Rectifier’s (SEE) RAD HARD technol-
ogy HEXFETs demonstrate virtual immunity to SEE
failure. Additionally, under identical pre- and post-ra-
diation test conditions, International Rectifier’s RAD
HARD HEXFETs retain identical electrical specifica-
tions up to 1 x 105 Rads (Si) total dose. No compen-
sation 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 operation within a few microseconds. Since
the SEE process utilizes International Rectifier’s pat-
ented 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 volt-
age control, very fast switching, ease of paralleling and
temperature stability of the electrical parameters.
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.
