SLVK222 August 2025 TPS7H5020-SP
During the SEB/SEGR characterization, the device was tested at room temperature of approximately 25°C. The device was tested under both the enabled and disabled mode. For the SEB-OFF mode the device was disabled using the EN-pin by forcing 0V (using CH # 1 of a E36311A Keysight PS). During the SEB/SEGR testing with the device enabled/disabled, not a single input current event was observed.
The species used for the SEB testing was 165Ho at 15MeV/nucleon and 169Tm at 19.5MeV/nucleon. For both ions an angle of 0° was used to achieve a LETEFF of ≈75MeV·cm2/mg (for more details refer to Ion LETEFF and Range in Silicon). The kinetic energy in the vacuum for 165Ho is 2.474GeV and 169Tm is 3.295GeV. Flux of approximately 4 × 104 to 1 × 105 ions×cm2/s and a fluence of ≈107 ions/cm2 was used for the run. Run duration to achieve this fluence was ≈2 minutes. The 6 production devices and 7 pre-production devices (same as used in SEL testing) were powered up and exposed to the heavy-ions using the maximum recommended bias conditions. No SEB/SEGR current events were observed during the 26 runs, indicating that the TPS7H502X-SP is SEB/SEGR-free up to LETEFF = 75MeV·cm2/mg and across the full electrical specifications.Summary of TPS7H502X-SP SEB/SEGR Test Condition and Resultsshows the SEB/SEGR test conditions and results.
