International 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
(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
voltage 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 Table 1, column 1, IRHF9230.
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.
High dose rate testing may be done on a special re-
quest basis using a dose rate up to 1 x 10
12
Rads (Si)/
Sec (See Table 2).
International Rectifier radiation hardened P-Channel
HEXFETs are considered to be neutron-tolerant, as
stated in MIL-PRF-19500 Group D. International Rec-
tifier radiation hardened P-Channel HEXFETs have
been characterized in heavy ion Single Event Effects
(SEE) environments. Single Event Effects character-
ization is shown in Table 3.
