Single-Event Transients (SET) Results

The TRF0208-SP was characterized for SETs from 9.62 to 81.6 MeV-cm2/mg (Table 5-1 provides more information) at 3.3V supply voltage. The device was tested at room temperature for all SETs runs. TRF0208-SP devices were thinned for proper heavy-ion penetration into the active circuits. Average flux of 105 ions/cm2-s and fluences of 107 ions/cm2 per run were used during the heavy ion characterization. The devices were tested under AC inputs. The SETs discussed on this report were defined as output voltages excursion that exceed a window trigger set on the MSO58B. Outputs of the TRF0208-SP were converted to SE using HL9402 balun and monitored. Test conditions used during the testing are provided in Table 8-1. Positive and negative upsets excursions were observed under AC test. For each upset the maximum, minimum, and transient recovery time were recorded. All upsets are recovered under 10ns. Weibull-Fit and cross section for the AC tests are shown in Figure 8-1 . The Weibull equation used for the fit is shown below, and parameters are provided in Table 8-2. To calculate the cross section values the total number of upsets (or transients) and the fluences where combined (add together) by LETEFF to calculate the upper bound cross section (as discussed in Appendix B) at 95% confidence interval. Worst case AC upset for each leg is shown in Figure 8-2. Though not observed during the testing, it is important to note that an SET event may result in output going up to saturation voltage.
