Tested with pulses tp=20 ms.
Valid provided that leads are kept at ambient temperature at a distance of 8 mm form case.
ZENER IMPEDANCE (ZZ) DERIVATION:
ZZT and ZZK are measured by dividing the ac voltage drop across the device by the
ac current applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.
4)
ZENER VOLTAGE (VZ) MEASUREMENT:
Nominal zener voltage is measured with the device junction in thermal equilibrium
at the lead temperature of 30°C
±1°C
and 3/8, lead length.
