MEGA RAD HARD
500Volt, 0.45, MEGA RAD HARD HEXFET Product Summary
International Rectifier’s RAD HARD technology
HEXFETs demonstrate excellent threshold voltage
stability and breakdown voltage stability at total
radiaition doses as high as 1x106 Rads(Si). Under
identical pre- and post-irradiation test conditions, In-
ternational Rectifier’s RAD HARD HEXFETs retain
identical electrical specifications up to 1 x 105 Rads
(Si) total dose. No compensation in gate drive circuitry
is required. These devices are also capable of surviv-
ing transient ionization pulses as high as 1 x 1012 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.
