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.

8. Include SZ-prefix devices where applicable.
