International Rectifier鈥檚 MEGA RAD HARD technology
HEXFETs demonstrate excellent threshold voltage sta-
bility and breakdown voltage stability at total radiation
doses as high as 1 x 10
6
Rads (Si). Under
identical
pre-
and post-radiation test conditions, International Rectifier鈥檚
RAD HARD HEXFETs retain
identical
electrical specifi-
cations up to 1 x 10
5
Rads (Si) total dose. At 1 x 10
6
Rads
(Si) total dose, under the same pre-dose conditions, only
minor shifts in the electrical specifications are observed
and are so specified in table 1. No compensation in gate
drive circuitry is required. In addition, these devices are
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 International Rectifier RAD HARD HEXFETs
has demonstrated virtual immunity to SEE failure. Since
the MEGA RAD HARD process utilizes International
Rectifier鈥檚 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 switching
power supplies, motor controls, inverters, choppers, au-
dio amplifiers and high-energy pulse circuits in space and
weapons environments.
