4. V BR measured at pulse test current I T at an ambient temperature of 25 ? C.
5. Z ZT and Z ZK are measured by dividing the AC voltage drop across the device by the AC current applied. The specified limits are for I Z(AC)
= 0.1 I Z(DC) , with the AC frequency = 1.0 kHz.
6. Surge current waveform per Figure 6 and derate per Figure 7
* Include SZ-prefix devices where applicable.
