Characteristics
International Rectifier Radiation Hardened HEXFETs
are tested to verify their hardness capability. The hard-
ness assurance program at International Rectifier uses
two radiation environments.
Every manufacturing lot is tested in a low dose rate
(total dose) environment per MlL-STD-750, test
method 1019. International Rectifier has imposed a
standard gate voltage of 12 volts per note 6 and a
V
DSS
bias condition equal to 80% of the device rated
voltage per note 7. Pre- and post-radiation limits of
the devices irradiated to 1 x 10
5
Rads (Si) are identi-
cal and are presented in Table 1, column 1,
IRHY7130CM. 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-radiation performance are
tested and specified using the same drive circuitry
and test conditions in order to provide a direct com-
parison. It should be noted that at a radiation level of
1 x 10
5
Rads (Si) no changes in limits are specified in
DC parameters.
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 neutron and heavy ion
Single Event Effects (SEE) environments. Single Event
Effects characterization is shown in Table 3.
