1)
Zener voltage is measured under pulse conditions such that TJ is no more than 2 OC above Ta
2)
ZZT is measured by dividing the ac voltage drop across the device by the ac current applied. The specified limits are for IZ
(ac) = 0.1IZ (dc) with the ac frequency = 1 KHz
3)
Tested with pulses tp = 20 ms.
