Radiation Performance of Rad Hard HEXFETs
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 presented in Table
1, column 2, IRH8250. 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

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.
