(5)

VZ measured at pulse test current IT at an ambient temperature of 25°C.

(6)

Surge current waveform per Figure 5 and derate per Figure 4.

(7)

ZZT is measured by dividing the AC voltage drop across the device by the AC current supplied. The specified limits are IZ(AC) = 0.1 IZ(DC), with AC frequency = 1 kHz.
