4.3.1 Surge current. Surge current, method 4066 of MIL-STD-750. IO = 0; VRM(W) = 0; IFSM = 275 A; six surges;
TA = 25°C; tp = 8.3 ms; one minute minimum time between surges.
NOTE: A shorter time between surges will be allowed as long as it can be demonstrated that ĆTJ ≤ 10°C, as
measured immediately prior to the first current pulse and immediately after the final current pulse.
