SLVK173 July 2024 TPS7H4011-SP
The purpose of this study is to characterize the single-event effects (SEE) performance due to heavy-ion irradiation of the TPS7H4011-SP. Heavy-ions with LETEFF of 75 MeV × cm2 / mg were used to irradiate four production devices. Flux of approximately 105 ions/cm2 × s and fluence of 107 ions / cm2 per run were used for the characterization. The results demonstrated that the TPS7H4011-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 trigger at 20% below nominal) and PWRGD (edge trigger at 500mV below nominal) were monitored to check for transients and SEFIs. The results showed the device is SET and SEFI free up to 75 MeV × cm2/ mg at T = 25°C.
