IRHNA57260SE, JANSR2N7473U2
Table 1. Electrical Characteristics @ Tj = 25°C, Post Total Dose Irradiation
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.
Radiation Characteristics
Fig a.
Single Event Effect, Safe Operating Area
International Rectifier radiation hardened MOSFETs have been characterized in heavy ion environment for
Single Event Effects (SEE). Single Event Effects characterization is illustrated in Fig. a and Table 2.
