SLVK327A July 2026 – October 2026 TPS7H1301-SP , TPS7H1302-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 Keysight E36311A). 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 169Tm at 19.5 MeV/nucleon (KSEE) and 165Ho at 15MeV/nucleon (TAMU). For both ions an angle of 0° was used to achieve a LETEFF of ≈75MeV·cm2/mg (for more details refer to Table 5-1). Flux of ≈105 ions/cm2/s and a fluence of ≈107 ions/cm2 per run was used. Run duration to achieve this fluence was ≈2 minutes. The 7 production devices (same as used in SEL testing) were powered up and exposed to the heavy-ions using the maximum recommended input voltage of 6.3V and both min and max VOUT values of -0.6V and -6V, respectively for TPS7H1301-SP and VOUT value of -1.8V for TPS7H1302-SP. No SEB/SEGR current events were observed during the 14 runs, indicating that the TPS7H130x-SP is SEB/SEGR-free up to LETEFF = 75MeV·cm2/mg. Table 8-4 shows the SEB/SEGR test conditions and results.

Using the MFTF method described in Single-Event Effects (SEE) Confidence Interval Calculations application report, the upper-bound cross-section (using a 95% confidence level) is calculated as:
σSEB ≤ 2.63 x 10-8 cm2/device for LETEFF = 75MeV·cm2/mg and T = 25°C.
