The threshold voltage remains within accptable operating limits over the full operating temperature and post radiation. This is achieved while maintaining single event gate rupture and single event burnout immunity. These devices are used in applications such as current boost low signal source in PWM, voltage comparator and operational amplifiers.

For footnotes refer to the last page 2 www.irf.com Radiation Characteristics Pre-Irradiation IRHLF770Z4 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. Table 1.
