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 3 and 4) 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.
