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 uses
two radiation environments.
IRHNA7264SE Device
Radiation Characteristics
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 stan-
dard gate voltage of 12 volts per note 6 and a V
DSS
bias condition equal to 80% of the device rated volt-
age per note 7. Pre- and post-radiation limits of the de-
vices irradiated to 1 x 10
5
Rads (Si) are identical and
are presented in Table 1. 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 comparison. It
should be noted that at a radiation level of 1 x 10
5
Rads
(Si), no change in limits are specified in DC param-
eters.
High dose rate testing may be done on a special re-
quest 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.
