Radiation Performance of Rad Hard HEXFETs
International Rectifier Radiation Hardened HEX-
FETs are tested to verify their hardness capability.
The hardness assurance program at International
Rectifier uses two radiation environments.

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
standard gate voltage of 12 volts per note 6 and a
V
DSS
bias condition equal to 80% of the device
rated voltage per note 7. Pre- and post-radiation
limits of the devices irradiated to 1 x 10
5
Rads (Si)
are identical and are presented in Table 1. 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-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
parameters.
High dose rate testing may be done on a special
request basis, using a dose rate up to 1 x 10
12
Rads
(Si)/Sec.
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.
