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 3 radiation environments.
Every manufacturing lot is tested in a low dose rate
(total dose) environment per MlL-STD-750, test
method 1019 condition A. International Rectifier has
imposed a standard gate condition of 12 volts per note
5 and a V
DS
bias condition equal to 80% of the de-
vice rated voltage per note 6. Post-irradiation limits
of the devices irradiated to 1 x 10
5
Rads (Si) are pre-
sented in Table 1, column 1, IRHNB7264SE. The val-
ues 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 comparison. It should be
noted that at a radiation level of 1 x 10
5
Rads (Si) the
only parameter limit change is V

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

characterization is shown in Table 3.
