The TPS7H5002-SP QMLP HDR exposure was
performed on biased and unbiased devices in a Co-60 gamma cell at TI facility in Dallas,
Texas. The un-attenuated dose rate of this cell is 175.827 rads(Si)/s (175.824 to
175.830 rad(Si)/s). After exposure, the devices were packed in dry ice (per MIL-STD-883
Method 1019.9 section 3.10) and full post-radiation electrical evaluation using Texas
Instruments ATE was conducted. ATE test limits are set per data sheet electrical limits
based on qualification and characterization data. Post-radiation measurements were taken
within 30 minutes of removing the devices from the dry ice container. The devices were
allowed to reach room temperature prior to electrical post-radiation
measurements.
