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

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 10

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.

International Rectifier Radiation Hardened HEXFETs
are tested to verify their hardness capability. The hard-
ness assurance program at International Rectifier
comprises three radiation environments.

Every manufacturing lot is tested in a low dose rate
(total dose) environment per MIL-STD-750, test
method 1019 condition A. International Rectifier has
imposed a standard gate condition of 12 volts per
note 5 and a V

bias condition equal to 80% of the

device rated voltage per note 6. Pre- and post- irra-
diation limits of the devices irradiated to 1 x 10

Rads

(Si) are identical and are presented in Table 1, col-
umn 1, IRHF7130. Post-irradiation limits of the devices
irradiated to 1 x 10

Rads (Si) are presented in Table

1, column 2, IRHF8130. The values in Table 1 will be
met for either of the two low dose rate test circuits that
are used. Both pre- and post-irradiation performance
are tested and specified using the same drive circuitry
and test conditions in order to provide a direct com-
parison.

High dose rate testing may be done on a special
request basis using a dose rate up to 1 x 10

Rads

(Si)/Sec (See Table 2)

International Rectifier radiation hardened HEXFETs
have been characterized in heavy ion Single Event
Effects (SEE) environments. Single Event Effects char-
acterization is shown in Table 3.
