International Rectifier Radiation Hardened MOSFETs are tested to verify their radiation hardness capability.
The hardness assurance program at International Rectifier 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.
