, MEGA RAD HARD HEXFET
International Rectifier’s MEGA 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 10
5
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 10
12
Rads (Si)/Sec, and return
to normal operation 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 indus-
try.
RAD HARD HEXFET transistors also feature all of
the well-established advantages of MOSFETs, such
as voltage control, very fast switching, ease of paral-
leling and temperature stability of the electrical pa-
rameters. They are well-suited for applications such
as switching power supplies, motor controls, invert-
ers, choppers, audio amplifiers and high-energy pulse
circuits in space and weapons environments.
