NOTE 1. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal zener voltage is measured with the device junction in thermal equilibrium with ambi-
ent temperature at 25°C.
NOTE 2. ZENER IMPEDANCE (Z Z) 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.
