10 Total Ionizing Dose (TID) From SEE Experiments

The production TPS7H4001-SP POL is rated to a total ionizing dose (TID) of 100 krad(Si). In the course of the SEE testing, the heavy-ion exposures delivered ≈10 krad(Si) per 10⁷ ions/cm² run. The cumulative TID exposure, for each device respectively, was always controlled to be less than 100 krad(Si). With the exception of the 17 units that were deliberately operated outside the SOA in an effort to capture the onset of DSEE, all 20/37 production RHA TPS7H4001-SP devices used in the studies described in this report stayed within specification and were fully-functional after the heavy-ion SEE testing was completed.
