Pre-Irradiation
Radiation Characteristics
IR HiRel Radiation Hardened MOSFETs are tested to verify their radiation hardness capability. The hardness assurance
program at IR HiRel is comprised of two radiation environments. Every manufacturing lot is tested for total ionizing dose
(per notes 5 and 6) using the TO-3 package. 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.
