(3) VZ measured at pulse test current IT at an ambient temperature of 25°C.
(4) Surge current waveform per Figure 5 and derate per Figure 6.
(5) ZZT is measured by dividing the AC voltage drop across the device by the AC current supplied. The specfied limits are IZ(AC) = 0.1 IZ(DC), with AC frequency = 1 kHz.
