Provisional Data Sheet No. PD-9.1444
400 Volt, 4.5
, (SEE) RAD HARD HEXFET
International Rectifier’s (SEE) 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 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 opera-
tion within a few microseconds. Since the SEE pro-
cess 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 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.
