International Rectifier鈥檚 P-Channel RAD HARD technology
HEXFETs demonstrate excellent threshold voltage stability
and breakdown voltage stability at total radiation doses as
high as 10
5
Rads (Si). Under
identical
pre- and post-radia-
tion test conditions, International Rectifier鈥檚 P-Channel 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. Single Event Effect (SEE) testing of Inter-
national Rectifier P-Channel RAD HARD HEXFETs has
demonstrated virtual immunity to SEE failure. Since the
P-Channel RAD HARD process utilizes International
Rectifier鈥檚 patented HEXFET technology, the user can ex-
pect the highest quality and reliability in the industry.
P-Channel RAD HARD HEXFET transistors also feature all
of the well-established advantages of MOSFETs, such as
voltage control,very fast switching, ease of paralleling 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-energy pulse circuits in space and weap-
ons environments.
