, MEGA RAD HARD HEXFET
International Rectifier’s RAD HARD technology
HEXFETs demonstrate excellent threshold voltage
stability and breakdown voltage stability at total
radiaition doses as high as 1x10

is required. These devices are also capable of surviv-
ing transient ionization pulses as high as 1 x 10

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 industry.
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.
