7 Single-Event Latch-up (SEL) Results
All SEL characterizations were performed with forced hot air to maintain the die temperature at 125°C during the tests. The device was exposed to a Silver (Ag) heavy-ion beam incident on the die surface at 0° incident angle for an effective LET of 56.1 MeV-cm2/mg. A flux of 105 ions/cm2-s and fluence of 107 ions/cm2 per run was used in all three runs. The device was powered up with maximum supply voltage of +3.45 V in most runs. In few runs device was tested at absolute maximum supply voltage of +3.7 V. During all runs the device was actively amplifying a single ended input signal at 100 MHz. Both differential outputs were independently terminated (SE) to 50 Ω .
Time duration to achieve this fluence was approximately 2 minutes. The SEL results and conditions are summarized in Table 7-1. No SEL events were observed under any of the three test runs, indicating that the TRF0208SEP is SEL-immune at a die-exposed temperature of T = 125°C and LET = 56.1 MeV-cm2/mg. A typical temperature and supply current vs time plot is shown on Figure 7-1.
