The purpose of this study is to characterize the single-event effects (SEE) performance due to heavy-ion irradiation of the TPS7H401x-SP. Heavy-ions with LETEFF of 75 MeV×cm2/mg were used to irradiate eight production devices. Flux of ≈105 ions/cm2/s and fluence of 107 ions/cm2 per run were used for the characterization. The results demonstrated that the TPS7H401x-SP is SEL-free up to 75 MeV×cm2/ mg at T=125°C and SEB/SEGR free up to 75 MeV×cm2/mg at T=25°C. Output signals including VOUT (3% window), SS_TR (edge negative trigger at 50% below nominal) and PWRGD (edge negative trigger at 50% below nominal) were monitored to check for transients and SEFIs. The results showed the device is SEFI free up to 75 MeV×cm2/mg at T = 25°C. SETs are characterized and discussed at LETEFF = 75 MeV×cm2/mg.
