8 Single-Event Transients (SET)

SETs are defined as heavy-ion-induced transients upsets on the VOUT, SS_TR, or PWRGD of the TPS7H4011-SP.

Testing was performed at room temperature (no external temperature control applied). The heavy-ion species used for the SET testing was Homium (165Ho) for an LETEFF = 75MeV × cm2/ mg, for more details refer to Ion LETEFF, Depth, and Range in Silicon. Flux of approximately 5 × 104 ions/cm2× s and a fluence of 1 × 107 ions/cm2, per run were used for the SET's characterization discussed on this chapter. Over the course of testing four devices, not a single transient or SEFI was recorded on any of the monitored signals indicating that the TPS7H4011-SP is SET/SEFI free up to LETEFF = 75MeV × cm2/ mg.

Waveform size, sample rate, trigger type, value, and signal for all scopes used is presented on Table 8-1.
