1)
O
Zener voltage is measured under pulse conditions such that T
J
is no more than 2 C above T
a
2)
Z
ZT
is measured by dividing the ac voltage drop across the device by the ac current applied. The specified limits are for I
Z
(ac) = 0.1I
Z
(dc) with the ac frequency = 1 KHz
3)
Tested with pulses tp = 20 ms.
