(3) VZ/VBR 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 and ZZK are measured by dividing the AC voltage drop across the device by the AC current supplied. The specfied limits are

(5) IZ(AC) = 0.1 IZ(DC), with AC frequency = 1 kHz.
