MEGA RAD HARD

60Volt, 0.015
, MEGA RAD HARD HEXFET
International Rectifier’s RAD HARD technology
HEXFETs demonstrate immunity to SEE failure. Ad-
ditionally, under
identical
pre- and post-irradiation
test conditions, International Rectifier’s RAD HARD
HEXFETs retain
identical
electrical specifications up
to 1 x 10
5
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 10
12
Rads (Si)/Sec, and return to normal
operation within a few microseconds. Since the RAD
HARD 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 voltage control, very fast switching, ease of par-
alleling and temperature stability of the electrical
parameters. They are well-suited for applications
such as switching power supplies, motor controls,
inverters, choppers, audio amplifiers and high-en-
ergy pulse circuits in space and weapons environ-
ments.
