Table 3. Single Event Effects
International Rectifier Radiation Hardened HEXFETs are
tested to verify their hardness capability. The hardness
assurance program at International Rectifier com prises
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 volt-
age per note 6. Pre- and post- irradiation limits of the
devices irradiated to 1 x 10
5
Rads (Si) are identical and
are presented in Table1, column1, IRHN9150. Post-ir-
radiation limits of the devices irradiated to 3 x 10
5
Rads (Si) are presented in Table 1, column 2,
IRHN93150. 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
Radiation Performance of Rad Hard HEXFETs
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
3 x 10

tion hardened P-Channel HEXFETs are considered
to be neutron-tolerant, as stated in MIL-PRF-19500
Group D.
International Rectifier radiation hardened P-Channel
HEXFETs have been characterized in heavy ion
Single Event Effects (SEE) environments. Single
Event Effects characterization is shown in Table 3.
