Radiation Performance of Rad Hard HEXFETs
IInternational Rectifier Radiation Hardened HEXFETs
are tested to verify their hardness capability. The hard-
ness assurance program at International Rectifier com
prises three radiation environments.
Every manufacturing lot is tested in a low dose rate (to-
tal 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- irradiation limits of the de-
vices irradiated to 1 x 10

Rads (Si) are identical and
are presented in Table1,column1, IRHNA9064.Post-ir-
radiation limits of the devices irradiated to 3 x 10

Rads
(Si) are presented in Table 1, column 2, IRHNA93064.
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 comparison. It should be
noted that at a radiation level of 3 x 10

to be neutron-tolerant, as stated in MIL-PRF-19500
