The effect of heavy-ion irradiation on the single-event effects performance of the radiation-hardness-assured (RHA) TRF0208-SP is summarized in this report. Heavy-ions with an LET_EFF up to 81.6 MeV-cm²/mg were used to irradiate two production devices in multiple runs. Flux up to 10⁵ ions/cm²-s and fluences up to 10⁷ ions/cm² at temperatures of 25°C (SET) and 125°C (SEL), were used for the characterization. Results demonstrate that the TRF0208-SP is SEL-free up to LET_EFF = 81.6 MeV-cm²/mg and 125°C, and the cross section for the SET is discussed.
