The parametric data for the THVD9491-SEP passes to 30krad(Si) HDR TID irradiation. The drifts of the electrical parameters through HDR were within the data sheet limits.

Overall, the THVD9491-SEP showed a strong degree of hardness to HDR TID irradiation up to 30krad(Si). The measurements taken post-irradiation for each sample set showed a marginal shift for most parameters at each dose level. The parameters that did show a greater degree of change between pre- and post-irradiation were still within the electrical performance characteristics specified in the data sheet electrical parameters. In accordance with MIL-STD-883K section 3.13.1.1, this device does not exhibit ELDRS effects due to every spec parameter post irradiation remaining below the pre-irradiation electrical specification limits at a low dose rate. For the datasheet electrical parameters and associated tests, see "THVD9491-SEP Datasheet".
